Relieving Fuel Pressure
CAUTION:
Fuel system is under approximately 39 psi. Use caution when relieving pressure on fuel system. Anytime fuel fittings are separated, a new conically shaped metal gasket (Part No. 1608786) should be installed. Do not reuse gaskets.
On models without Schrader valves on rear of fuel rail, place shop towel over fitting to be removed and loosen fitting slowly to relieve fuel pressure. On models with Schrader valves, remove protective cap from pressure fitting and loosely install Adapter (J-5420) on fitting. Arrange shop towel or container so that discharged fuel will be contained. Slowly tighten adapter, until pressure is relieved.
