Fuel Pump: Service and Repair

WARNING: Do not smoke, carry lighted tobacco or open flame of any type when working on or near any fuel related component. Highly flammable mixtures are always present and may be ignited, resulting in possible personal injury.

CAUTION: Fuel supply lines will remain pressurized for long periods of time after engine shut down. This pressure must be relieved before servicing of the fuel system is begun. A valve is provided on the throttle body for this purpose. Remove the air cleaner and relieve system pressure by using Rotunda pressure gauge tool T80L-9974-A or equivalent and drain the system through the drain tube.
