Fuel Tube/Ouick-Gonnect Fittings
Procautions
@ Do not smoke whils working on the fuel
syst6m, Koop open flames away from your work ar9a.
The fuel tube/quick-connect fittings assembly connects
the in-tank fuel pump with the fuel feed pipe. For remov-
ing or installing the fuel pump and fuel tank, it is neces-
sary to disconnect or connect the quick-connect fittings.
Pay attention to following;
. The fuel tube/quick-connect fittings assembly is not
heat-resistant; be careful not to damage it during weld-
ing or other heat-generating procedures.
. The fuel tube/quick-connect fittings assembly is not
acid-proof; do not touch it with a shop towel which
was used for wiping battery electrolyte. R€place the
fuel tube/quick-connect fittings assembly if it came
into contact with electrolyte or somethino similar.
. When connecting or disconnecting the fuel tube/quick-
connect fittings assembly, be careful not to bend or
twist it excessively, Replace it if damaged,
A disconnected quick-connect fittings can be reconnected,
but the retainer on the mating pipe cannot be reused once
it has been removed from the pipe. Replace tha retainer

!@ Do not smoke while working on the fuel
syst6m. Keep open flames away from your work area.
1. Disconnect the battery negative cable.
2. Remove the fuel fill cap to relieve fuel pressure in
the tank.
3. Relieve fuel pressure (see page 11-178).
4. Check the fuel quick-connect fittings for dirt, and
clean if necessary.
5. Hold the connector with one hand and press down
the retainer tabs with the other hand. then pull the
connector off.
NOTE:
. Be careful not to damage the pipe or other parts.
Do not use tools,
. lf the connector does not move, keep the retainer
tabs pressed down, and alternately pull and push
the connector until it comes off easily.
. Do not remove the retainer from the pipe; once
removed, the retainer must be replaced with a
new one.

4.Align the quick-connect fittings with the pipe. and
align the retainer locking pawls with the connector
grooves. Then press the quick-connect fittings onto
the pipe until both retainer pawls lock with a click-
Ing sound.
NOTE: lf it is hard to connect, put a small amount of
new engine oil on the pipe end.
5. Make sure the connection is secure and that the pawls
are firmly locked into place; check visually and bypulling the connector.
Reconnect the battery negative cable, and turn the
ignition switch ON (ll). The fuel pump will run for
about two seconds, and fuel pressure will rise. Repeat
two or three times, and check that there is no leakage
in the fuel supply system.
