Quick Connect Fuel Fittings
Notes:
Some fuel lines have quick connect fittings, which are designed to speed up the installation and removal of fuel lines (Fig. 3).
Quick connect fittings consist of a metal casing, a black plastic release ring, a metal locking retainer, and internal O-rings.
Warning: Fuel system pressure must be released before disconnecting any fuel system component.
1.
Disconnect the negative battery cable.
2.
Remove the fuel tank gas cap to release fuel tank pressure.
3.
Perform the Fuel System Pressure Release Procedure.
4.
Remove any loose dirt from quick connect fittings.
Caution: Wrap shop towels around hoses to catch any gasoline spillage.
5.
To remove the fuel tube nipple from a quick connect fitting, pull back on the fitting while pushing in on the plastic ring. To aid in disassembly, an
open end wrench may be used to push the plastic ring in.
6.
Cover the quick connector to prevent contamination.
Assembly
1.
Inspect the quick connect fitting to ensure the black plastic release ring is in the OUT position. If the locking retainer is stuck in the RELEASE
position, due to mushrooming of the release ring or dirt accumulation, the fitting should be replaced.
Caution: The fuel tube nipples must be lubricated with clean 30 weight engine oil prior to connecting the quick-connect fitting.
2.
Lubricate the male end of the fuel tube with 30 weight engine oil.
3.
Insert fuel tube nipple into quick connector fitting. When the fuel tube nipple is inserted into the quick-connect fitting, the shoulder of the nipple is
locked in place by the locking retainer and the internal O-rings seal the tube.
4.
Pull back on the quick connect fitting to verify the connection is secure. The tube should be locked in place. If the connection is not complete,
make sure the black plastic release is not causing the locking retainer to jam in the release position.
Caution: When using the ASD Fuel System Test, the ASD relay and fuel pump relay remain energized for 7 minutes or until the test is stopped, or until
the ignition switch is turned to the Off position.
5.
Using a scan tool, activate the ASD relay, to pressurize the fuel system, and check for leaks.
