I had a fuel gage on a M151-A1 that always showed empty. I swaped the
gauge, as it was the easiest to get to, with the same results. After I
removed the sender unit I found fuel leaking from the float.
I drilled a small hole in the end if the float and drained out the fuel
then washed it in water. I then soldered a model aircraft brass tube in the
hole and attached a short piece of plastic tubing. Blowing in the tube
while submursing the float in water reveaveled a hair line crack along the
indentation where the float attaches to the sender arm. I then soldered the
crack and after retesting pinched off the end of the tube.
After a few months the same problem occured. Disassembly revealed another
crack had developed on the float body a short distance from the orginal. I
repaired the second crack and replaced the unit. Afew months later same story.
My analyisis was that tempurature cycling work hardend the float material
so I replaced the entire assembly with a NOS. After telling my story to a
National Guard mechanic I found out that thay had to replace many sender
units on the MUTT jeeps, so I guess that the problem is a, "design oversight".
