For those of you who may be able to help me. While fueling my truck, I noticed that the fuel gauge (arrow indicator) was pass the "F" of the gauge almost horizontal. I decide to switch to the rear tank and noticed that the gauge remained on the same position. But the problem doesn't stop there. The switching of front to rear tank blew the fuse (position 6). I replace the fuse and gets blown. I removed the fuel tank switch valve and the short is gone. For those of you who may know the reason for this problem, I will appreciate any help possible.
