    Low Pressure (Fuel Tank to Engine) The production system uses a return less variable flow/pressure system that has been incorporated in the Chevrolet Performance engine control kit. A return less fuel system reduces the internal temperature of the fuel tank by controlling the speed of the fuel pump and not returning hot fuel from the engine to the fuel tank.
  • Página 4 The variable pressure/flow oil pump must be controlled by the ECM in order to maintain proper lubrication and minimize excessive oil delivery to the cylinder heads and PCV system. There are several devices on the LT1 that use oil pressure to maintain proper functionality.
  • Página 5 The engine coolant should route to the lower portion of the radiator, or inlet hose of the coolant pump. Heat is then removed by the engine radiator. Reference the 2019 Camaro LT1 for additional parts.
