key of the fuel suction plate No.1.
(d) Apply MP grease to the entire interior surface of the fuel
pump gauge retainer.
(e) Align the triangle mark on the new fuel pump gauge re-
tainer with the ºSº mark on the fuel tank while pushing
down the fuel suction tube. Attach the fuel pump gauge
retainer.
(f) Rotate the fuel pump gauge retainer by hand. Use an SST
to tighten the fuel pump gauge retainer by turning it one
and a half times. The triangle mark on the fuel pump
gauge retainer must be positioned between the ºAº and
ºMAX.º marks on the fuel tank.
