{"product_id":"fx-350-high-pressure-fuel-pump-kit","title":"FX-350 High-Pressure Fuel Pump Kit","description":"The Spool Performance FX-350 High-Pressure Fuel Pump Upgrade represents the next evolution in fueling technology, significantly surpassing its predecessor, the FX-200, in both performance and efficiency. Engineered to deliver fuel at an impressive 35Mpa, this kit boasts a substantial increase over the FX-200's 25Mpa. This boost in pressure directly translates to a 40% increase in injector flow rate, ensuring ample fuel availability for combustion in high-demand, performance-oriented engines. The higher pressure also aids in superior fuel atomization, a critical factor in direct-injected engines for achieving more efficient and complete combustion.\n\nThis upgraded fuel pump is essential for M177 motors where the stock High-Pressure Fuel Pump (HPFP) is a limiting factor for tuning and increasing output. The FX-350 adds approximately 90% more flow capacity, raising fueling limits and enabling the use of larger turbos and\/or higher ethanol concentrations. The kit includes two FX-350 pumps, an optional Ethanol Content Monitor kit with a mobile app, a Bosch-spec 10-micron high-flow fuel filter, upgraded fuel lines, and all necessary installation hardware. The included 10-micron filter unit provides excellent filtration without impacting low-side fuel pressure, safeguarding the HPFP and injectors from debris.\n\nInstallation of the FX-350 pumps requires calibration changes, which must be applied before starting the vehicle to prevent potential damage and voiding the warranty. Spool Performance can provide calibration details to your tuner or help you connect with experienced tuners. Custom tuning is mandatory to achieve maximum performance tailored to your specific vehicle setup and environmental conditions. It is also crucial to ensure proper low-pressure fueling upgrades are in place, as inadequate low-pressure fuel delivery can lead to detectable damage to the HPFP and void warranties.","brand":"Spool Performance","offers":[{"title":"Default Title","offer_id":52866388558136,"sku":"SP-FX350-M178","price":6499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687689608.webp?v=1787907023","url":"https:\/\/store.motormia.co\/products\/fx-350-high-pressure-fuel-pump-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
