Quick Fuel Technology 30-400 User Manual

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!!

TUNING AND ADJUSTMENT:

If the pump does not pickup fuel within 30 seconds, stop and prime the pump. The pump should not be operated dry for
extended periods of time. Pressure to the regulator is controlled by the bypass valve screwed into the outlet side of the
fuel pump. Loosen the check nut on the bottom and the top barrel will turn clockwise or counter clockwise. Clockwise will
increase pressure and counter clockwise will decrease pressure. Pressure can be checked at the pump from the 1/8 NPT
tapped hole in the pump body. 18 to 20 PSI is usually sufficient for a hard leaving car plumbed as suggested. Make sure
to tighten the check nut after adjusting the fuel pressure. Check for leaks to insure your safety.

NOTE: BARREL SHOULD NOT BE MORE THAN 4 1/2 TURNS FROM SEATED (CLOCKWISE) POSITION OR

LEAKAGE WILL OCCUR.

The QFT™ 400 will provide more fuel volume to the carburetor than other fuel pumps, so your jetting requirements may
have changed. Re-jet the carburetor either one size richer or leaner until the car shows either an increase or decrease in
performance. Proceed in the direction that shows the most improvement until the performance falls off. Then return to
the jet size that gave you the quickest ET and MPH.

MAINTENANCE:
The following tips should be followed to insure maximum performance from your QFT™ 400 Fuel Pump:

1. Fuel pressure to the regulator and after the regulator should be checked before every racing event to assure

proper fuel system operation.

2. If the vehicle is to be stored for long periods, it is recommended that the pump be operated, with fluid flowing, for
several minutes weekly to keep fluid passages clean and the bypass working freely.

3. Rebuild Kits are available – P/N 30-7302 Pump Rebuild Kit and P/N 30-7307 Pump Body & Seal Assembly.
