FUEL DELIVERY Cleanfire System Overview Fuel Pump (700)
700 CFI The Cleanfire fuel system uses fuel pump (A) that is located inside the fuel tank, fuel rail (C) with in-line fuel filter (B), and injectors (D)The fuel pump will create pressure in the system and deliver the fuel mixture to the injectorsThe injectors get signal from the engine controller unit (ECU) and sprays into the engineThe only maintenance that is needed with this system is that the fuel filter (B) needs to be changed every 1,000 miles (1600km)Fittings should be inspected for cracks or leaksDo not use pliers or other tools that may damage fuel lines when installing or removing fuel railFuel travels from the fuel pump through the fuel filter and to the injectorsAny fuel that is not delivered through the injectors will travel back to the fuel tank through the return lineThis fuel pump on this system is non-serviceable and can not be replacedIf fuel pump fails, the whole fuel tank assembly must be replacedFUEL PUMP: Located inside tankIt provides system with fuel at 58psi (4bar) pressureIf the fuel pressure is suspect to be defective apply 12 VDC to the fuel pump prime (Red (#1) and the Brown (#3) wires) and check for audible fuel pump operation as well as fuel rail pressureThe fuel pump should sound when pumping and the pressure should show 58psi (4 bar) pressurePIN COLOR ITEM
