The piston and cylinder assembly is the largest volume possible within the stock MQB fuel pump body. Top-quality components and our strict QC process ensure extreme reliability. Increase your fueling overhead and enjoy worry-free HPFP operation.\n\n\n\n\n\n\n\n\n\n\n\n\n\nADDED DISPLACEMENT\n\n\n\n\nYour HPFP is an integral part of the MQB platform direct injection (DI) system and provides exceptionally high-pressure fuel (exceeding 2900psi) to the injectors. When running turbo upgrades or ethanol fuel, the stock HPFP internal volume becomes the limiting factor when increasing power. 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\nFLOW TESTING\n\n\n\n\nUpgrading to IE's HPFP reliably increases the flow rate of the high-pressure pump for more tuning headroom to increase power safely. The result is a maximum gain of 38.58% over stock!\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. Tolerances are hand-verified using specialized measurement tools and verified down to 0.00005 of an inch to ensure reliability and proper function. These extreme manufacturing and QC processes are the foundation that has built ","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/IEFUVN1_IE_MQB_MK7_8V_HPFP_KIT__1.webp?v=1770315178","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/IEFUVN1_IE_MQB_MK7_8V_HPFP_KIT__2.webp?v=1770315178","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/IEFUVN1-4IE_MQB_HPFP_Tool_3.webp?v=1770315178"],"price":472.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:22.277Z"},"share_url":"https://firestarter.network/l/lst_PZTYb3ui","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
