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.
