2003 6.0L Models Only), cont’d.

F. Remove the fuel line from the outlet (front) of

the fuel filter. Remove the tube from the plastic

retainer holding it so that it can be rotated freely.

Some models may vary from the photo slightly.

Follow the same procedure, taking care to mount

the pump so that the hard line is not stressed.

G. Making sure the O-ring is seated on the threaded

end of the supplied fitting, install into the outlet

(front) of the fuel filter and tighten.

H. Making sure the O-ring is seated on the tube end

of the fuel line (removed from the filter) thread

the bump tube into the fitting installed on the

outlet of the fuel pump and tighten.

I. Route the free end of the hose connected to the

fuel pump inlet to the fitting previously installed

on the fuel filter outlet. Use the supplied hose

clamp to secure the hose on the barb fitting. Try

to make the bends as large as possible, so as to

avoid kinking the hose. Secure the hose using

the wraps and tighten all of the hose clamps.

J. Install the supplied adel clamps onto the fuel

pump and mark holes to be drilled for #12 sheet

metal screws. Drill an 11/64” hole at each loca-

tion. Using the supplied black 12-gauge wire

with yellow ring terminal connectors, install one

end under the sheet metal screw nearest the

electrical terminal side of the fuel pump. Attach

the other end of the ground wire to the (-) ter-

minal of the fuel pump. Secure to the frame as

shown in Fig. 9-e. Tighten both adel clamps.

K. Attach the previously routed red wire to the posi-

tive terminal of the fuel pump using the yellow

ring terminal connector.
