Do not use galvanized lines, fittings orfuel tanks. Carefully clean all
fuel system components before putting the engine into operation.
Any dirt or contamination may cause major damage to the fuel
injection system.
Beginning with Spec S, a new fuel filtration system
accommodates both primary and secondary fuel
filters on a common mounting casting which is bolted
to a newly designed oil fill
tube.
Theengine cannot be
run with either filter loose or missing, thus ensuring
proper filtration at all times.

is
essential.
Use number 2 battery cables of the proper length to
limit voltage drop.

CONNECTIONS
Batteries for engines equipped with optional flywheel
alternators must be negatively grounded. A 30 amp
fuse protects the rectifier should the battery be
connected with reverse polarity (Figure 6). On early
models without fuse, destruction of the rectifier will
result.
Connect the remaining battery cable to the larger
terminal on the starting motor solenoid (Figure 5).
