The Qfi fuel pump in the Qfi 500 Master Kit System
includes a 100 micron screen pre-filter built into the pump (It is a white filter you can see just below the
threads of the pump’s Inlet fitting), which keeps the coarse particles from reaching the pump.
From your tool box…What tools do you need?
Here is a list of the tools you will need for the installation project. These are basic hand tools you most
likely have in your tool box.
Screwdrivers: Straight blade and Phillips head
Wrenches: Open/Closed box-end, Ratchet/Socket set advisable but optional, HEX-head wrench set,
Oxygen Sensor wrench
3/8 in. electric drill with assortment of high speed drill bits
Hole saw
Soldering gun

Required optional parts:
If you have purchased the Qfi 500 System Base Kit (QFT-500BD), these parts are required.
An EFI-rated adjustable pressure regulator (QFT Model 50-5016).
High pressure continuous duty EFI fuel pump -- must be rated to deliver 40-45 psi and 45 gallons per
minute (gpm/255 liters/hr - lph). We recommend the Quick Fuel Technology Model 50-5011 pump.
(We also recommend a 100 micron pre-filter between the fuel tank and the fuel pump inlet to
protect the fuel pump. A sock-type filter in the fuel tank is acceptable. The pre-filter prevents
coarse debris from entering the pump and damaging it.) HINT: The higher the filter’s micron number
rating, the COARSER the filter.
A 10 micron (or finer) fuel filter between the fuel pump and the Qfi throttle body assembly (QFT
Model 50-5015).
A 100 psi fuel pressure gauge (QFT Model 50-5012).
