Remote Fuel Pump
Figure 8-8 illustrates the remote fuel pump kit for
Model HGJAA. The Model HGJAD kits include fill
neck adaptors for fuel supply and return connec-
tions at the tank and are specific to each make and
model of vehicle. The right kit must be used. Follow
the instructions in the kit when replacing a pump as-
sembly. Figure 8-6 illustrates the 2-pin remote
pump wiring connector and in-line fuse and Fig-
ure 8-7 the fuel supply and return fittings at the gen-
set.
WARNING
Gasoline is flammable and explo-
sive and can cause severe personal injury or
death — Do not smoke — Keep flames, sparks,
pilot lights, switches, arc-producing equipment
and all other ignition sources away from fuel,
fuel components and areas sharing ventilation
— Keep an ABC fire extinguisher handy.
Fuel Pump Flow Test: Disconnect the fuel return
line at a convenient point between the genset and
supply tank and be prepared to collect the fuel in a
gallon container. Prime the genset for exactly one
(1) minute taking care not to spill any fuel. The whole
fuel system, exclusive of the injectors, is probably in
good working order if fuel flow is approximately
1 quart (0.9 liter) per minute and fuel pressure is
approximately 45 psi. A much higher fuel pressure
indicates a blockage in the fuel system. Make sure
to reconnect the fuel return line.
