LT4 Style HPFP Kit w/Lines

The 1150-250 High-Pressure Fuel Pump (HPFP) is a universal, LT4-style core featuring an 11.5mm piston and capable of operating at 250 bar. It offers a significantly higher pressure rating than the standard GM LT4 production pump.

While it closely resembles the OEM GM LT4 pump (Part Numbers: 12711668 or 12694529), this version features a key difference: it uses an AN06 male-threaded low-pressure inlet instead of the OEM 3/8" SAE quick-connect fitting. This threaded AN connection allows for greater flexibility and easy integration into custom fuel systems using standard AN hardware.

Our pump kit includes all necessary hardware and accessories for seamless installation in our C8 twin turbocharger package.
