Fuel Pressure Release: Service and Repair
WARNING: To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing fuel system
components.
After relieving system pressure, a small amount of fuel may be released when servicing fuel lines or connections. In order to reduce the chance
of personal injury, cover fuel line fittings with a shop towel before disconnecting, to catch any fuel that may leak out. Place the towel in an
approved container when disconnect is completed.
When servicing the fuel system use the following precautions:
a.
Put a "CAUTION FLAMMABLE" sign in the workshop.
b.
Be sure shop is supplied with an adequate fire extinguisher.
c.
Be sure to disconnect the negative battery cable before any service work is done.
d.
Use a suitable container to catch any fuel that may leak from system during service.
e.
Always relieve fuel system pressure before disconnecting any lines.
f.
If the key must be turned ON while servicing fuel system, always disconnect or disable ignition, to insure no sparks occur near fuel vapors.
PROCEDURE:
Tool required: J34730-1 Fuel Pressure Gauge or equivalent.
1.
Disconnect the negative battery cable, to avoid fuel pump turn on, if an accidental attempt is made to start the engine.
2.
Loosen the fuel filler cap to relieve tank vapor pressure.
3.
Connect the fuel pressure gauge to the pressure connection. Wrap a shop towel around the fitting while connecting the gauge to avoid spillage.
4.
Install bleed hose into an approved container and open the valve to bleed the system pressure. Fuel connections are now safe for servicing.
5.
Drain any fuel remaining in the gauge into an approved container.
When repair to the fuel system has been completed, START the engine and check all connections that were loosened for leaks.
