When designing a big power FI system, you will want the flexibility of a rising rate FPR, as you will want to manipulate the fuel pressure and volume behind your larger injectors. Convert your return-less fuel system into a more flexible return system with integrated inline pump and rising rate fuel pressure regulator.
HPA’s engineered solution ensures the venturi system within the saddle bag gas tank of the 4-motion chassis is not disrupted. Our installation kit includes a CAD-designed distribution block which incorporates a high flow fuel pump, filter, and connection point for both the feed and return line.
A fuel bowl adaptor (to be welded onto your factory fuel rail) will house the included 4.0bar FPR. HPA also includes a relay pack and harness to ensure that the correct voltage is supplied for the in-line pump.
Designed for MK5 R32, MK2 TT, and A3 applications.
