These instructions will help you operate and maintain your pump. This owner's manual covers the EZ-8RV and EZ-8RVS, 12-volt electric gear pumps. This manual covers models with manual nozzle.
Notice: This pump is not intended to be used with an automatic nozzle.
An automatic bypass valve prevents pressure build up when the pump is on with the nozzle closed.
To avoid motor damage, do not run the pump more than 5 minutes with the nozzle closed.
The rated duty cycle of this pump is 15 minutes ON and 30 minutes OFF.
Allow the pump to cool for 30 minutes.
FUEL TYPE
This pump is designed for use only with gasoline (up to 15% alcohol blends such as E15), diesel fuel (up to 20% biodiesel blends such as B20) and kerosene.
Do not use this pump for dispensing any fluids other than those for which it was designed. To do so may damage pump components and will void the warranty.
This pump is designed to operate on a typical 12-volt DC automotive electrical system.
The pump is designed to operate with 12-volts DC at the motor leads and the ratings are determined at this voltage. Performance may vary due to length of power cord, battery condition or output from vehicle charging system that will affect system voltage.
Do not leave the
system running without fluids. "Dry running" can damage the pump. If the
system fails to deliver fuel after 15 to 20 seconds, turn the system
off and refer to the Troubleshooting Section.
Do not pump the tank completely dry, as contaminants from the bottom of the tank may enter the pump.
SAFETY INSTRUCTIONS
Observe all safety precautions concerning safe handling of petroleum fuels.
To
ensure safe operation, all fuel transfer systems must be properly
grounded. Proper grounding means a continuous metal-to-metal contact
from one component to the next, including tank, bung, pump, meter,
filter, hose and nozzle.
Care should be taken to
ensure proper grounding during initial installation and after any
service or repair procedures. For your safety, please take a moment to
review the warnings in this manual.
To prevent physical injury, observe precautions against fire or explosion when dispensing fuel.
Do not
operate the system in the presence of any source of ignition including
running or hot engines, lighted cigarettes, or gas or electric heaters.
Observe precautions against electrical shock when operating the system.
Serious or fatal shock can result from operating electrical equipment in damp or wet locations.
Inspect external pump wiring regularly to make sure it is correctly attached to the battery. To avoid electrical shock, use extra care when connecting the pump to power.
Avoid prolonged skin contact with petroleum
fuels. Use protective goggles, gloves, and aprons in case of splashing
or spills. Change saturated clothing and wash skin promptly with soap
and water.
Observe precautions against electrical shock when servicing the pump.
Always disconnect power before repairing or servicing.
Never apply electrical power to the system when any of the coverplates are removed.
INSTALLATION
This pump is designed to self-prime with dry gears.
Make
sure all threaded fuel connections are wrapped with three to four turns
of Teflon® tape or a pipe thread sealant approved for use with
petroleum fuels.
Clean the tank interior of all dirt and debris.
Make sure the tank is vented. A vent cap rated at 3 psi or less is recommended.
Suction line design and size is important for optimum pump performance. GPI requires suction line to be 3/8" miminum diameter.
Pump must be mounted within the clearance lines of the vehicle and protected from road impact damage.
Install Electrical Connections
A
grounding connection is provided. It is identified as a green colored
binding head screw in the electrical cavity. Connect these pumps only to
a 12-volt DC power source.
Do not attempt connection to a 24-volt DC, 115-volt AC or 230-volt AC power source.
For installation in unclassified areas, a flexible power cord, fuse and strain relief grip should be used.
NOTE: These components have not been evaluated as part of the UL Listed Equipment and are not intended for use in a Hazardous (Classified) Location.
To install the power cord, remove the electrical coverplate. If necessary, trim the power cord to the desired length. Strip 3 to 4 inches (7.5 to 10 cm) of outer insulation from the power cord end. Then strip 1/2 in. (1.3 cm) of insulation from the power cord wires. Slide the strain relief grip onto the power cord so that the threaded end of the strain relief grip faces the stripped power cord wires. Insert the power cord through the 1/2 inch NPT connection on the back of the pump. Using wire nuts, connect black wire to black and red wire to red in the pump's electrical cavity. Position the wires inside the electrical cavity and tighten the strain relief grip securely. Make sure surfaces are clean. Install the coverplate and tighten securely.
!!! WARNING !!!
Carefully route the power cord to the battery, protecting the power cord from hot surfaces, sharp edges or anything that could damage the power cord, resulting in a short circuit.
!!! WARNING !!!
Pump
must have circuit protection per ANSI/RVIA 12. A 20-amp slow-blow fuse
is a minimum requirement to protect the motor and power cord. Install
fuse in the red wire of the power cord adjacent to the battery. Connect
the fuse to the positive (ungrounded) side of battery. Connect black
wire to the negative (grounded) side of battery.
!!! DANGER !!!
If pump is to be installed in a Hazardous (Classified) location, it must
be installed by a licensed electrician and conform to National Fire
Protection Association (NFPA) codes 30 and 70. You as the owner, are
responsible for seeing that the installation and operation of your pump
complies with NFPA codes as well as any applicable state and local
codes. Rigid conduit must be used to install wiring. Note that the lead
wires are factory-sealed isolating the motor from the junction box.
Install Hose and Nozzle
After sealing threads, tighten the hose into the pump outlet and the
nozzle on the hose.
Failure to follow these wiring instructions may result in death or
serious injury from shock, fire or explosion.
OPERATION
ALWAYS FOLLOW SAFETY INSTRUCTIONS WHEN OPERATING THIS EQUIPMENT.
Before each use, repair leaks around seals or connections. Make sure hoses are in good condition and connections are tight.
MAKE SURE THE PUMP IS PROPERLY GROUNDED.
Repair any corroded or damaged wiring before use. Ensure the tank contains enough fuel. Make sure the fuel is not contaminated with debris.
To Dispense Fuel
Depending
on the model, turn pump on by activating the power circuit on the RV or
by lifting up on the switch lever. Insert the nozzle into the receiving
tank and squeeze the handle to start fuel flow. When done, release the
nozzle handle and turn off the pump.
This pump is designed to be self-priming. If fuel is not delivered
within 15 to 20 seconds, turn the pump off and refer to priming
information in the Troubleshooting Section.
An automatic bypass valve prevents pressure build up when the pump is on with the nozzle closed. To avoid pump damage, do not run the pump more than 5 minutes with the nozzle closed. After running the pump for a maximum of 15 minutes, allow it to cool for 30 minutes.
Auxiliary Temperature-Limiting Device
The motor is provided with an internal auxiliary temperature-limiting device. Excessive motor heat can trip the device. It resets automatically after the motor has cooled.
MAINTENANCE
This
pump is designed for minimum maintenance. Motor bearings are sealed
and require no lubrication. Inspect the pump and components regularly
for fuel leaks and make sure the hose and power cord are in good
condition. Keep the pump exterior clean to help identify leaks.
Do not
use this pump for water, chemicals or herbicides. Dispensing any fluid
other than that listed in this manual will damage the pump. Use of the
pump with unauthorized fluids will void the warranty.

Fittings (Size / Placement / Materials)
Drainage (Fittings / Placement)
Tank Placement (Inside / Outside)
Gray Water Tank Calculation
Multiply (fresh tank size) x 1.15 (1 . 15%) = Tank needed
30 x 1.15 (15%) = 34.50
30 x 1.50 (50%) = 45
I have only so much room how many gallons can I get in that space?
We do not recommend sizes or verbally give measurements please look at the Water Tank List located at the top of each webpage to see all tanks Class A Customs currently manufactures.
How are the water tanks measured?
Please be sure to look at the photos provided with each item as measurements and fitting placements will be included. Note the measurement of the tanks do not include the fittings, this will add extra length to the tank.
~ Fittings ~
Due to increased sales we are no longer
able to offer custom fittings on water tanks.
Where are the fittings located in the tank? What kind of fitting are in the tank?
Our Stock Tanks come with 4 fittings all located on the same side of the tank. Be sure to look at the tank photos and description to clarify fittings.
Can I cut a hole in the tank and glue another fitting in?
No, fitting are spun welded into the tank, friction between the fitting and the tank causes both to melt and permanently seal, no additional glues or sealants are used to install the fittings.
The residue left by putting the fittings in place is part of the material the tanks and fittings are made from and may spider crack or flake off over time, this in no way harms the tank or causes any usage issues.
Is that a fitting or a clean-out on the side?
Each tank will come with at least one vent hole made during the manufacturing process, a permanently mounted patch is placed over this hole this is not a fitting and does not unscrew.
~ Plumbing ~
Have a certified technician install all parts to prevent product damage and personal injury.
All water tanks we carry must be vented, they are not pressurized tanks.
You must allow air to move in and out when filling and emptying the tank. Do NOT fill the tank directly from a pressurized line (garden hose), this is not a safe option and will explode the tank. We recommend using a fill dish to allow for gravity feeding of the tank, please review our plumbing example for more information.
What fittings will I need?
This will depend on how you are setting-up your tank and will vary by application. Please view our Plumbing Category for information on loose fittings we carry.
At this time Class A Customs only installs the following fittings into our Fresh / Gray tanks
.5" NPT Female
1.5" NPT Female
1.25" Outer Diameter x 2" Long Smooth Pipe (Boss Fitting)
It is recommended to use plastic male fittings with plastic female fittings to avoid damaging the threads, metal thread fittings can crush the plastic threads.
1.25" spout fitting can be used for water inlet or drain
What is a fill dish?
The fill dish is located on the outside of your unit so that you can easily add water to your tank without the need of opening a compartment or climbing under your unit. You can find the fill dishes in the Plumbing Category.
For adding water to the Water Tank you need a Gravity Fill Dish, the hose rests in the port it does not screw onto the port this allows you to place a garden hose into the Gravity Fill Dish port without making a sealed connection so the supply is not pressurized.
For using water directly from a garden hose you need a City Fill Dish, the hose makes a sealed connection and the water supply is pressurized, you can not hook this to your water tank and you do not need to go through your water pump.
We carry Gravity Fill Dishes, City Fill Dishes and Combo Fill Dishes that have both gravity and city, the benefit of having both is you can have a water tank of fresh water but if you go to a location that supplies pressurized water (campground - fair - etc.) you do not need to use your water tank supply of water you can simply use the water provided. Be sure to look at the provided example plumbing diagram for more reference.
But what if I only turn the garden hose on half way?
Customers who do this still explode the tank because you can not determine the pressure of the water flowing only the amount of water.
I am not using a fill dish how can I fill the tank?
We recommend you place a fitting in the tank that will allow you to rest the hose in to fill, not make a sealed connection, you can then cap this when not in use. You can use an elbow fitting to allow you the fill the tank to capacity, use an elbow with a screen secured over it to vent the tank.
Can I put a cap on and off of the tank?
If you are needing to use a fitting by adding and removing a cap, remember tank must be vented allowing air in/out during use, we recommend you place a fitting in the tank and a cap on that fitting in order to prevent damage to the tank fitting.

~ Installing & Bracing ~
The tank looks like the side is bowed, is it safe?
Due to the manufacturing process all the tanks especially the larger in size will have a bowing to the walls, when the tank is filled the tank will expand out removing the inward bow, we recommend laying all tanks on a level surface (this can be angled) and bracing the tanks. For larger tanks it is recommended to brace all side walls with plywood or metal, we do not recommend using ratchet straps on the tanks alone as this is a large amount of weight on a thin strip and may cause cutting into the tank.
Tank Average Thickness
All tanks will vary on thickness but on average they are .219 or 7/32" thick.
Can I stack the water tanks on top of each other?
No, do not place anything on the tanks, if you need to stack the tanks you will need a weight bearing shelf between them.
Do I need to brace the water tank?
It is recommended to brace all side walls with plywood or metal, we do not recommend using ratchet straps on the tanks alone as this is a large amount of weight on a thin strip and may cause cutting into the tank.
Can I set the tank up on end?
Yes, you can place the tank on any side, you will need to brace the tank and run a food grade pipe or hose down inside to reach the bottom of the tank. For easier use fittings can be moved and additional fittings added. You will need to fill-out the tank form to show the placement and once confirmed your order will be processed the next business day.
Can I mount the tank under the trailer?
Can I hook more than one tank together?
Yes, you will need to check with a certified plumber to see what fittings and set-up will work best for your unit, remember to vent each tank.
This is an example only, installation will vary depending on your unit.
Sanitize each tank prior to use to remove any debris from the manufacturing process. Tanks are made in a warehouse so maybe dusty or scuffed, this does not effect the use or safety of the tank, wipe with a damp cloth to remove surface dust or scuffs.
