FUEL PUMP
Removal/Installation
1. Disconnect the electrical lead from the negative
battery terminal.
2. Remove the toolbox cover and the side cover
from the left side as described in Chapter Fourteen.
3. Roll the boot back from the electrical connec-
tors.
4. Disconnect the two-pin fuel pump connector (A,
Figure 91
) from its harness mate.
NOTE
During removal, label each hose and
its fitting, and note how a hose is
routed through the frame. This as
sures that each hose will be connected
to the correct fitting and properly
routed during assembly.
5. Disconnect the inlet hose (B,
Figure 91
) and
outlet hose (C) from their fittings on the fuel pump.
6. Slide the fuel pump from its rubber grommet,
and remove it.
7. Installation is the reverse of removal. Note the
following:
a. Securely seat the fuel pump in its mounting
grommet.
b. Connect the inlet (B,
Figure 91
) and outlet
hoses (C) to the proper fittings on the pump.
Troubleshooting
Refer to Chapter Two.
Operational Test
Check the operation of the fuel pump by applying
battery power directly to the fuel pump.
1. Remove the toolbox cover and the side cover
from the left side as described in Chapter Fourteen.
2. Roll the boot from the connectors on the toolbox
panel.
3. Disconnect the two-pin fuel pump connector (A,
Figure 91
) from its harness mate.
4. Disconnect the fuel pump outlet hose (C,
Figure
91
) from the fitting on the pump. Connect a test
hose to the outlet fitting on the pump and feed the
hose into a container.
5. Disconnect the input hose (B,
Figure 91
) from
the fitting on the fuel pump and connect an auxiliary
fuel tank to the pump’s input fitting.
6. Use jumpers to connect the battery to the fuel
