Low Pressure Fuel System - All Others: Notes

Fuel is pumped from the fuel tank to the primary fuel filter by the electric fuel pump. Pressurized and filtered, approximately 379 kPa (55 psi) during engine idle, the fuel is pumped through the fuel supply line to the secondary fuel filter (the secondary fuel filter housing is located on the front left side of the engine). The filtered fuel leaves the secondary fuel filter and flows to the high pressure pump. Fuel bled off by the high pressure pump and fuel rail pass through the fuel cooler before returning to the fuel conditioning module.

Fuel bled off by the fuel injectors is recycled to the inlet side of the secondary fuel filter.
