ISSUE:
Some fuel spillage may occur while servicing the dual function reservoir when the fuel lines are disconnected. This happens because the dual
fuel tank switching valve does not completely shut off the fuel supply.
ACTION:
To minimize the possibility of fuel spillage when servicing the dual function reservoir (DFR), use the following service procedure.
1.
Remove the six (6) plastic fuel line retaining clips from the original dual function reservoir. Do not remove the DFR from the frame at this time.
2.
Remove one fuel line at a time and immediately reinstall on the corresponding port of the replacement DFR (F1UZ-9B263-A).
a. Install one new plastic fuel line retaining clip (N802241-S).
b. Make sure that it is properly seated.
3.
Repeat Step # 2 for the remaining fuel lines.
4.
Remove the original DFR from the frame rail.
NOTE:
SEND THE ORIGINAL DUAL FUNCTION RESERVOIR TO THE WARRANTY PARTS RETURN CENTER, 1285 S. MILL ST.,
PLYMOUTH, MI 48170.
5.
Install the new DFR, with all fuel lines and retaining clips attached, to the frame rail.
6.
Start the engine and check for fuel leaks.
7.
Switch the fuel tanks and repeat the leak check.
