{"product_id":"big-bore-12-0mm-high-volume-fuel-pump","title":"Big Bore 12.0mm High Volume Fuel Pump","description":"The Lingenfelter Big Bore Direct Injection High Volume Fuel Pump is engineered to overcome the fuel flow limitations of stock GM direct injection V8 engines, enabling significant performance increases. With a 12.0 mm bore, this pump provides over 30% greater flow than the stock L86 \u0026amp; LT1 pumps and nearly 10% more than the LT4 pump. When paired with a Lingenfelter GT35 camshaft featuring a 7.85 MM fuel pump lobe, it delivers 40% more flow than a stock LT4 pump and camshaft combination.\n\nPrecision machined and assembled using brand new production LT1 fuel pump cores, this fuel pump features a DLC coated bore and piston. It is compatible with production LT1 and LT4 fuel pump lobes, as well as aftermarket higher lift lobes, though some aftermarket designs may require a lash cap or a revised spring for optimal lifter control. The pump is 100% hot tested for guaranteed performance and functionality, and each unit is individually serial numbered. Its maximum recommended operating pressure is 15 MPa (2175 PSI), and it requires a consistent low-side fuel pressure of 68 PSI or greater. This pump is also E85 compatible.\n\nThis high-volume fuel pump is designed for high horsepower GM Gen V V8 and V6 direct injection engines, including E85 conversions. It fits applications such as the 2014-2019 C7 Corvette (LT1), 2015-2019 C7 Z06 Corvette (LT4), 2016-2021 Camaro SS (LT1), 2016-2019 CTS-V (LT4), 2017-2021 ZL1 LT4, and various 2014-2018 Silverado\/Sierra and 2015-2018 Suburban\/Tahoe\/Yukon\/Escalade models equipped with specific engines (LV3, L83, L86).","brand":"Lingenfelter","offers":[{"title":"Default Title","offer_id":52686624751928,"sku":"L710166914","price":2545.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/659230513.jpg?v=1784875410","url":"https:\/\/store.motormia.co\/products\/big-bore-12-0mm-high-volume-fuel-pump","provider":"MOTORMIA","version":"1.0","type":"link"}
