Fuel sending unit and fuel gauge issue.....

[13Echo70271]

Hi Blue, does your tank have brass or metal threaded inserts for the sending unit screws? My plastic Moeller tank has brass inserts for the screws. I had the same issue last year. Once I cleaned out the corrosion using a small pick and WD40, I found the inserts and carefully ran a bottoming (nearly flat bottom) tap thru to chase the threads and clean them. If you need to, you could tap for slightly larger screws. With the new rubber gasket and clean surfaces mine worked out well, no more leaks , no more smell. Good luck, TJ

Screw holes on tank have metal threads in current position, so rotating would be worse - screws would go into the plastic tank, not the metal threads.

Now with special fuel resistant apoxy applied too, it may be fixed. Will see when I get home.

Still don't like it - should be absolutely secure. It screws down tight - the 5 screws all tight, not stripped, but somehow when pressured at full with fuel, it was weaping out around the rubber gasket.

Didn't realize it was plastic... Was thinking aluminum

How about lock tight on the screws, and using a cork gasket??

You sure it is weeping around the gasket? That is what I thought but it was actually coming from the screw threads

Seems fixed now - used the fuel resistant goop and re tightened.
Filled to over flow and it's dry at the sending unit.
Ran a new ground wire, so gauge working too.......got to keep it all good since it's a rare and extremely valuable V21 series :)

Yeah but how fast will it go?!?!
