Our premium HPFP internals kit for your Audi 4.0TT V8 engine upgrades both factory high-pressure fuel pumps with performance high-flow internals. Leading-quality components and strict QC process will reliably increase the fuel delivery from your stock fuel system with a set of 11.67mm pistons providing additional fuel support for larger turbos and ethanol fuel.
The 4.0TT’s high-pressure fuel pumps supply high-pressure fuel (exceeding 2900psi each) to the direct-injeciton fuel system injectors. When running turbo upgrades, especially with ethanol fuel blends, the stock HPFPs internal volumes become a limiting factor when increasing power. IE’s HPFP internals install into your factory pump housings and increase the bore and piston size of the pump internals, allowing more flow, delivering more fuel, and allowing for more horsepower & torque from your hardware and tuning upgrades.
HPFP TOOL
Disassembly & assembly of the factory HPFP housing requires a specialty tool to thread the assembly housing into the pump body. We have designed and manufactured ours to fit directly to 1/2″ drive socket and torque wrenches. This offers better leverage for unthreading the body and reliable torque spec to complete the install process without any hassles to make the job easy.
