Installing the Filler Neck Tee in the Filler Tube
6B-1. Cut filler tube as illustrated in figure 20, removing
½
inch of hose. Loose assemble
clamps on each end of filler tube before the filler tube is pushed in.
6B-2. Insert the “Return Fuel Filler Tube” assembly (P/N 001-4A-1-0200) in the filler tube.
INSTALL THE FILLER TUBE WITH ARROWS, WHICH ARE STAMPED IN THE PART,
POINTING TOWARD THE TANK!! SEE FIG 21

Properly tighten clamps.
NOTE: Some 01-04 trucks have a plastic tube inside of the fill tube, be sure NOT to cut this clear tube.
You will need to only cut the outer rubber hose then slide the plastic tube inside the return fill tube
supplied in the kit, then clamp the rubber fill tube onto the adapter as shown in figure 22.
6B-3. Assemble one end of the hose (Reference section 5) using Fuel line end FQC3890 and
plug it into the “Return” J2044 fitting installed in the AirDog® (Figure 23). A “click” will
be heard once the fitting is properly connected.
6B-4. Run the fuel line along the frame as mentioned in step 5-3 to the filler neck tee. Cut the
fuel line to length and insert fuel line end FQC12S per step 5-1. Once the connector is
installed, connect it to the male J2044 fitting in the filler neck tee (001-4A-1-0200). A
“click” will be heard once properly connected.
