Fuel Pressure Release: 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.
Release pressure from fuel system at the fuel pressure relief valve using tool No. T80L-9974-B or equivalent. When relieving fuel pressure, crank
engine with fuel pump electrical connector disconnected.
