Stock ATS-V fuel systems are already starting to have difficulty keeping up above 500 whp. On every ATS-V we tune we see fuel pressure drop as we turn up the boost. The more boost we add, the worse the problem gets. Tapout Tuning is here to resolve those issues and we can provide the support for all your fueling needs!
We offer two different stages of Low Pressure Fuel Pumps designed to satisfy a wide range of applications. The Tapout Stage 1 and Stage 2 LPFPs will help to prop up your entire fuel system, compounding the gains of aftermarket high pressure fuel pumps and/or fuel cams. The best part? There is no special tuning required for our LPFPs.
The Tapout Stage 1 LPFP will support up to 675 whp on regular gasoline and the Stage 2 LPFP supports up to 950 whp on gasoline and 675 whp on E85. These are the fuel pumps that can make your horsepower dreams a reality and we are here to support that every step of the way.
Check out this screen shot, which shows our fuel system easily maintaining 3,200 psi from 22 to 24 psi of boost through 158 mph on full E85:
