QFT™ 300 FUEL PUMP

P/N 30-300

The QFT™ 300 is a completely rebuildable electric fuel pump. The QFT™ 300 features a non-adjustable internal bypass to regulate pump pressure. Before installing your QFT™ 300 pump, PLEASE READ THE INSTRUCTIONS

THOROUGHLY. This pump is designed for off highway and competition use only. Any usage in street driven vehicles is strictly prohibited. QFT™ recommends the use of fuel pressure regulator 30-7025.

PUMP INSTALLATION:

Mounting

Your QFT™ 300 Fuel Pump should be as close to the fuel tank as possible. The fuel pump inlet should be level or below the fuel pickups if at all possible.

THE PUMP SHOULD NEVER BE MOUNTED IN THE DRIVER'S COMPARTMENT OR NEAR ANY HOT ENGINE COMPONENTS.

It should be mounted on a solid member, such as a chassis, in a vertical position; motor on top. Do not allow the motor housing to touch any metal parts on the vehicle. This will affect the motor and pump performance.

Inlet

The fuel pump should be fed by a single #10 or equivalent line from the tank. This may require rework of your existing fuel cell. A QFT™ 5000 (P/N 30-7007) fuel filter should be installed before the pump as it will prolong pump life and does not restrict flow.

Outlet

The outlet side of the pump, going to the regulator, should be a single #8 or equivalent line.

WARNING: DO NOT BLOCK THE VENT, RETURN LINE OR PUMP FEED. MAKE SURE THAT THE SYSTEM IS LEAK FREE AT ALL CONNECTIONS...YOUR SAFETY DEPENDS ON IT!

Wiring

BEFORE MAKING ELECTRICAL CONNECTIONS, DISCONNECT THE POSITIVE TERMINAL FROM THE BATTERY.

Your QFT™ 300 Fuel System should be connected to a fully charged 12 or 16 volt battery. A fuel pump, like any other electrical accessory, will only perform at its best when given adequate voltage. The black wire is a ground (-) and the remaining wire is a switched hot lead from a (+) 12 or 16 volt source. If wired incorrectly, the pump will run backwards and will not pump. A relay MUST be used for best performance and lower current draw from the battery. A 12 gauge wire should be used on the pump power supply and a 16 gauge wire from the switch to activate the relay. For best performance, keep all wiring runs as short as possible. Many electrical boxes now being sold will have circuits and fuses wired for smaller twin pumps, which is adequate if a relay is used. Power wiring to the pump should be capable of handling 25 amps as this will take care of the start-up voltage surge.

WARNING: ALL WIRING CIRCUITS SHOULD BE FUSED!!
