GM LT4 High Side Fuel Pump (LT1, LT4, L83, L86 Engines)

Helpful Tip: It has been known for some time that the LT direct injection engines are limited on fuel. To date the best combo seems to be using FIC’s 30% over injectors, stock LT4 high side fuel pump, inline low side fuel pump, and a 32%+ camshaft lobe. The Lingenfelter high side pump while still a good pump is limited to a smaller fuel pump lobe than the factory LT4 pump, and has been known to not produce as much volume as the above stated combo.

  • High horsepower GM Gen V V8 and V6 direct injection engines including LT4, LT1, L86, L83 and LV3 E85 conversions of GM Gen V V8 and V6 engines
