Questions and Answers

will this increase power with stock injectors?
View Staff Answer 

The FASS FA F15 125G ADJUSTABLE 125GPH FUEL PUMP will not INCREASE horsepower but will help to SUPPORT more horsepower in comparison to the stock fuel pump.

What's the difference between this fuel pump and FASS T F14 125G Titanium Series 125GPH Fuel Air Separation System
View Staff Answer 

The FASS FA F15 125G ADJUSTABLE 125GPH FUEL PUMP is JUST an adjustable fuel pump system. This kit will not include a water separator or fuel filter.

The FASS T F14 125G TITANIUM SERIES 125GPH FUEL AIR SEPARATION SYSTEM is a complete fuel and air separation system which will include both a fuel filter and water separator.
