3. 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 souno.
NOTE: lf it is hard to connect, put a small amount of
new engine oil on the pipe end.

Make sure the connection is secure and the pawls
are lirmly locked into place; check visually and by
pulling the connector.
RETAINER
Reconnect the battery negative cable, and turn the
ignition switch ON (ll) the fuel pump wjll 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.

Adjustment
NOTE:
a To check the clutch interlock switch and clutch
switch, see section 23.
a The clutch is self-adjusting to compensate Ior wear.
CAUTION: ll there is no clealance between the master
cylinder piston and push rod, the release bearing is held
against the diaphragm spring, which can result in clutch
slippage or other clutch problems.
1. Loosen locknut A, and back off the clutch switch
(or adjusting bolt) until it no longer touches the clutch
peoal.
2. Loosen locknut C. and turn the push rod in or out
to get the specified stroke (@) and height {O) at the
clutch Dedal.
3. Tighten locknut C.
4. Turn the clutch switch (or adjusting bolt) until it con-
