Tapout ATS-V Low Pressure Fuel Pump**

Description

The OEM ATS-V LPFP will flow 215 lph @ 70 psi and can support up to 550 whp on gasoline. It is not compatible with E85.

Tapout Stage 1 LPFP will help to prop up your entire fuel system, compounding the gains of aftermarket high pressure fuel pumps and/or fuel cams. This is the pump we recommend for Purple Belt Performance Package cars. It can support E0 to E85 up to at least 20 psi with OEM turbos, and E0 to E70 with 25 psi on OEM turbos. No special tuning is required for our LPFPs. The Tapout Stage 1 LPFP increases flow by 23% to 435 lph with no back pressure and 265 lph @70 psi. We include a brand new ATS-V fuel pump housing, retrofitted with a new ZL1 fuel pump. Unlike some of the other LPFPs available in this market, Tapout Stage 1 LPFP includes the correct length pickup tube for proper scavenging in the ATS-V fuel tank.

Installation takes a few hours with a helper. First the car must be lifted. Next, drop the exhaust system, driveshaft and gas tank. Replace entire fuel system bucket on passenger side. Then reinstall everything.

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.

 

The Tapout LPFP can be added to any of the above to provide a little extra padding or safety margin.  This unit will not increase overall fuel flow as a standalone modification, since the HPFP is the weakest link in the chain.
