Fuel sending unit ???
well, the sending unit crapped out again, same gromet everytime, seems like the gas warps it which causes it to leake.
Got a new one to replace it and now Im having trouple with it leaking around the o ring/ lockin ring, have drained the tank and resituated the o-ring gasket 3 times now with no luck.
Can I use some sort of gasket forming sealant around the tank/sending unit? Will that work to help seal the pieces together and stop the leake?
anyone have suggestions??
the sending unit pushes up against the tank with an o ring/gasket in between and they are pressed in by a locking ring which you twist on to its stop, seems like im not getting a good seal from the o ring, the locking ring goes on snug so i dont know what else to try........
Thanks

Re: Fuel sending unit ???
Sorry about the problem. Sounds like you've been troubleshooting this for a while.
Is there anyway you could get a heavier duty FSU so you stop having issues with the same grommet ?
As for the o-ring not getting a good seal, I've never had issues with adding RTV to help seal. Also, when you re-install it, it is getting secured evenly and firm enough to compress the o-ring, right?

Def feels like theres enough pressure to compress o ring evenly, someone on MF suggested getting a new locking ring when u switch out FSU's so I will try that next, just tried for the 4th time and same SH*T happened agained, house smells like gas once more..............

That ring is a bitch on the classics. Main reason for leaking is 1. dirty mating surface, 2. slippage/unseating of the ring while installing the lock ring. Most of teh time it will bind and then unseat.
Best way I found was to clean the surface really good than put some petrolium jelly on the ring so it slides nice when you tighten the lock ring.

Re: Fuel sending unit ???
update from last weekend, got the unit in and its working
Tried the jel but I think Dad hit the issue by using the pliers on the "ears" that hold the locking ring in place, seems to help hold it on snug. New unit has a thicker gromet so hopefully that helps prevent the same issue again. If the weather holds hope to take her for a spin to Kent Island sunday morn....
