These USA-engineered and manufactured parts will reliably transform your stock pump housing into a high-flow fuel pump for use on dual pulley ECU tunes to provide enough flow for ethanol fuel blends. The 11.67mm piston is the largest sized diameter possible within the fuel-pump body.\n\n\n\n\n\n\n\nDESIGNED & MACHINEDIN THE USAIN-HOUSE PRECISION\n\n\n\n\n\n\nUPGRADEDINTERNAL KITFOR YOUR STOCK PUMP\n\n\n\n\n\n\nHIGH-PRESSUREDUAL PULLEY E40FUELING SUPPORT\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nLEADING FEATURES\n\n\n\n\n\nHPFP internal DIY kit -upgrade your stock pump internals\nHPFP upgrade for ethanol tunes\nReliably adds a larger fuel ceiling for increased flow\nThe piston diameter increased to 11.67mm\nLargest stroke volume available\nBroken-in and bench tested on in-house pump dyno\nConstant diameter piston design for long-life operation\nRetains OE spring to avoid increased camshaft wear\nTool steel DLC-coated pin\nNitrided tool steel cylinder\nMolybdenum disulphide impregnated leak-free seal\nStainless steel seal body\nBuna-N rubber oil-resistant o ring\nIndividually tested and verified for extreme tolerances\nEngineered, designed, & manufactured in the USA\n\n\n\n\n\n\n\n\n\n\n\nADDED DISPLACEMENT\n\n\n\n\nThe 3.0TFSI HPFP is an integral part of the direct injection fuel system and provides exceptionally high-pressure (exceeding 2900psi) to the injectors. When running dual pulley upgrades on ethanol fuel, the stock HPFP internal volume becomes the limiting factor. IE's HPFP internals install into your factory pump housing and increase the bore and piston size of the pump internals, allowing more flow, delivering more fuel, and allowing for more horsepower & torque.\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nRELIABILITY\n\n\n\n\nEvery piston and cylinder is CNC machined to exacting sizes, assembled, and measured as a matching set in-house.
