the tank and the fitting at the top of the fuel
pump points 90° toward the centerline of the
machine.
2. Seat the fuel pump/sending unit into the opening
in the tank (
Figure 80 and Figure 81 ).
3. Install the seal and nut over the fuel
pump/sending and onto the neck of the fuel tank
and tighten the nut hand tight (
Figure 80 ).

Note:
Ensure that the locking sleeve of the
fuel-hose coupling secures the coupling to the
pump fitting.
