The B9 2.0T’s high-pressure fuel pump (HPFP) is laser-welded shut and non-upgradable. By swapping the stock HPFP with a VW MK7 2.0T vacuum pump housing and HPFP, you can upgrade to the iE HPFP MQB Internal Performance Kit, which ensures the necessary fuel delivery for ethanol power.\n\niE TrueFlex Sensor Harness Kit\niE B9/B9.5 2.0T POWERlink Tuning Suite\n\niE MK7 upgraded HPFP Internal Kit\nOEM MQB HPFP (PN: 06L 127 027 C)\nOEM vacuum Pump Housing (PN: 06L 145 100 N)\nOEM vacuum Pump Gasket (PN: 06H 103 121 J)\n(2x) OEM HPFP Bolts (PN: N 911 287 01)\n(3x) OEM vacuum Pump Bolts (PN: N 107 394 01)\n\nNote: iE does not offer OEM part numbers; these must be sourced from your local dealership or online factory parts retailers.\n\nFITMENT DETAILS\n-TrueFlex tuning is compatible with 2017-2020 2.0T model years only and is incompatible with the new 2021+ ECU variations.\n-Compatible with Quattro (AWD) models only and is incompatible with front-wheel-drive (FWD) vehicles.\n-Tr","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/IEELCK3_01_720x_357be454-9d0f-461c-b574-848515a33b6c.webp?v=1745954153","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/IEELCK3_02_720x_6871684e-50bf-4913-b61d-2662f1acafb6.webp?v=1745954153","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/IEELCK3_04_720x_154262ad-ca72-4fa4-a4a1-383e85dc9bda.webp?v=1745954153","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/IEELCK3_05_720x_96884d92-248a-4343-8a20-4240463da4e7.webp?v=1745954153","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/IEELCK3_06_720x_89caf7cb-916c-40df-ba50-957c3f4b936b.webp?v=1745954153"],"price":241.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:29.001Z"},"share_url":"https://firestarter.network/l/lst_6citG4A_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
