Installation Instructions for 30-125-1 & 30-125-1R Electric Fuel Pump
The QFT 125 GPH fuel pump is designed for drag race applications and is not well suited for continuous operation such
as over the road vehicles or industrial applications where there is little down time. If you use this pump on an application
that requires operation for extended periods of time it will shorten the life of this pump.
Warning: this is a high pressure fuel pump (14 P.S.I.) and requires a fuel pressure regulator to be
mounted between the fuel pump and carburetor!
This electric fuel pump is designed to push fuel forward in the vehicle and is very ineffective at “pulling” fuel.
Therefore, the fuel pump should be mounted in the rear of the vehicle, near the fuel tank and positioned so the inlet
side of the pump is gravity fed, that is, below the fuel tank itself.
This fuel pump should not be mounted in the trunk or an enclosed area!
NOTE: The two ports on this fuel pump are marked “IN” and “OUT”. Be certain to position the fuel pump correctly.
1. The pump should also be mounted on a solid component of the frame, positioned vertically so the motor is on top. If you
do not have an in-line filter now you should make provisions for the replacement of a fuel filter between the fuel tank and
fuel pump. Two fuel filters would be highly recommended.
2. Check for possible interference with suspension and/or chassis components through the full range of travel.
3. Check the lower portion of the pump in your chosen location - be certain it does not have a ground clearance problem
or could possibly come in contact with debris that could be kicked up by the tire.
4. It is also recommended that all fuel lines be metal and you should avoid the use of rubber hose. Rubber hose in this
location can be hazardous and the use of it is not advised. Route fuel lines away from any potential heat source, chaffiing,
or road debris. Avoid tight bends and undersized fittings throughout the fuel line routing process.
5. Using the mounted bracket as a template, center punch and drill two holes to mount the pump. Note: the pump bracket
slots are sized for 5/16” bolts.
6. Electrical connection is standard, the black wire is ground and the orange wire is positive. This pump will draw
approximately 3 amps although in some applications it could draw up to 5 amps under severe load. To achieve optimum
performance it is crucial the pump receive battery voltage (13.8 volts approx.) at all times. You may consider using a relay to
reduce the amperage load on the vehicle or chassis wiring. It is also strongly advised to use an oil pressure safety switch to
shut the pump off if the engine is not running.
7. Always set the pressure regulator (see your pressure regulator instructions) before attempting to start the engine. Always
use a fuel pressure gauge and check the gauge for accuracy often.
8. Fuel pump performance problems or failure is usually due to one of two problems: dirt and/or water. The clearances in a
rotary vane fuel pump are extremely close and do not tolerate debris or corrosion - the presence of either element will severely
impact the performance of your pump. Typically the fuel pressure will begin to fluctuate and the electrical amperage draw will
increase. If you follow these instructions and perform routine maintenance on the fuel filter you can minimize future problems.
