{"product_id":"high-pressure-fuel-pump-upgrade-kit-2-0tfsi-ea113","title":"High Pressure Fuel Pump Upgrade Kit, 2.0TFSI EA113","description":"The VIS Motorsport High Pressure Fuel Pump Upgrade Kit provides a necessary solution for engines modified beyond OEM power levels by addressing fuel delivery limitations. The factory high-pressure fuel pump (HPFP) can experience pressure loss under load; this kit replaces the internal piston and sleeve assembly to increase fuel volume displacement by over 55-75% compared to stock. These components are manufactured from 34mocr11 special aged steel, featuring three-stage heat treatment and nitriding for maximum durability.\n\nKey specifications include a piston surface hardness of 760-860 HV10 and microscopic clearance tolerances validated by CMM (Coordinate Measuring Machine). The design features a piston head optimized for directional fuel flow and utilizes an OEM-style spring keeper to prevent premature wear on the cam follower. By improving flow, this kit also reduces the duty cycle of the N276 solenoid, extending its operational lifespan.\n\nInstallation requires specific care. Do NOT fit these internals into a pump that has been removed from a hot, running engine, as the thermal expansion difference can cause the internals to seize. These components are strictly compatible with genuine Hitachi-manufactured VAG HPFPs; they are not compatible with Pierburg aftermarket pumps due to internal manufacturing differences. Professional installation and verifying the condition of the camshaft lobe and cam follower are strongly recommended.","brand":"VIS Motorsport","offers":[{"title":"Default Title","offer_id":52664065720632,"sku":"VIS.EA113.STG1","price":425.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687535128.png?v=1784332701","url":"https:\/\/store.motormia.co\/products\/high-pressure-fuel-pump-upgrade-kit-2-0tfsi-ea113","provider":"MOTORMIA","version":"1.0","type":"link"}
