QFT™ 400 FUEL PUMP

P/N 30-400

You have bought the QFT™ 400 - the ultimate in state-of-the-art electric fuel pump. It will provide a fuel flow of 400

gallons per hour. This pump is different from the one you are accustomed to, so please READ THE INSTRUCTIONS

THOROUGHLY and follow them to insure maximum performance from your QFT™ 400 Fuel Pump. THIS PUMP IS

DESIGNED FOR COMPETITION USE ONLY. ANY USAGE IN STREET DRIVEN VEHICLES IS STRICTLY

PROHIBITED. QFT™ recommends this pump be used with the 30-7023 regulator.

PUMP INSTALLATION:

Mounting

The best location for mounting your QFT™ 400 Fuel Pump in the vehicle is 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. A mounting bracket comes with the fuel pump. 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 #12 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 #10 or equivalent line.

Bypass

The return line should be fed with a single #8 or 1/2" line. The return should expel the bypassed fuel into the liquid rather

than into the air space of the fuel cell. This will prevent aeration of the fuel. All fuel tanks and cells should have fuel cell

foam installed to prevent fuel slosh.

WARNING: DO NOT BLOCK THE RETURN, VENT, 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™ 400 Fuel Pump 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

not move any fuel. 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!!
