5105 fuel tank leak update

[Jim in LA]

I posted Nov 6 regarding a possible cracked fuel tank. I inspected the fuel sending unit wiring connection on the bottom of the tank and found it could be turned by hand. I had replace this part about 12 years ago at a cost of around $120.00. Today s price $292.26 plus $8.00 for the gasket. I put 5 gallons in the tank and so far no leaks. Not a good location for the connector as limbs,vines, and other stuff can snag the wiring harness which I suspect happened in both cases. I still have an electrical issue that involves a common wire connection to the sending unit,PTO/key on alarm, and the tachometer sensor. Shop manual shows common connection, just a matter of tracing them out. Right now fuel gauge shows 3/4 full with only 4-5. gallons in the tank. It appears that the problem may be corrosion at the interconnections and possibly the common ground point.

Run a temporary ground lead to the sender from a ''good'' ground and see what happens.

MAY ''fix'' the other ground issues, as well.

Probably wouldn't be a bad idea to
fabricate some kind of guard to prevent
snags.
