Install Fuel Tank
WARNING
The fuel tank empty weight is approximately 225 pounds and is awkward to remove
from the MTRCS frame. Use 5-6 persons to remove tank to prevent personal injury.
NOTE
Due to the tight clearances of the fuel tank, it may be necessary to remove the fuel
tank filler neck to gain the needed clearance to slide the tank into the MTRCS frame.
If you need to remove the filler neck, perform steps 1 through 3.
1. Remove six screws (Figure 1, Item 27), lock washers (Figure 1, Item 29), and washers (Figure 1, Item 28)
securing filler neck flange (Figure 1, Item 26) to new tank (Figure 1, Item 9).
2. Cut sealant away from filler neck flange (Figure 1, Item 26).
3. Carefully remove filler neck flange (Figure 1, Item 26) as needed to break seal and remove filler neck flange
(Figure 1, Item 26).
NOTE
When installing the fuel tank, make sure that the liquid level gauge is facing the
outside of the MTRCS frame.
4. Install fuel tank with fuel gauge orientated to the outside of the frame (Figure 1, Item 9) into position on frame.
5. Install four screws (Figure 1, Item 5), new lock washers (Figure 1, Item 6), washers (Figure 1, Item 7), and nuts
(Figure 1, Item 8) to attach fuel tank (Figure 1, Item 9) to frame.
6. Tighten fuel tank mounting hardware (WP 0091).
CAUTION
Make sure that filler neck flange mounting area is free of sealant and other debris
before installing filler neck flange into tank. Failure to do so can result in a poor
sealing surface and possible leaks.
7. Apply a light bead of RTV around the outside of the filler neck flange (Figure 1, Item 26).
8. Install filler neck flange (Figure 1, Item 26) and secure to tank using six screws (Figure 1, Item 27), new lock
washers (Figure 1, Item 29), and washers (Figure 1, Item 28).
9. Connect 1/4-inch fuel line (Figure 1, Item 3) to tank inlet elbow (Figure 1, Item 4).
10. Install inlet elbow (Figure 1, Item 2) onto tank.
11. Connect 3/8-inch fuel line (Figure 1, Item 1) to tank inlet elbow (Figure 1, Item 2).
12. Connect fuel sending unit electrical connector P4/J4 on wire harness (Figure 1, Item 35).
