Time to give up on the Thermoquad?

I agree with RF, rebuild it. NAPA can get a kit for you, I would suggest replacing the floats as well (sold separately). Check the bottom of the wells, the little plastic piece, you might want to pull them off and re-glue them in place using some good epoxy. There are small O rings in the bottom of the wells, are they there?

I took an old TQ and rebuilt it and it runs great on my car.

If you do rebuild it, pull the wells and put them back on with some good epoxy and let it sit for 2 or 3 days to fully cure before you put it back together.

What epoxy would you suggest? The stuff I used to make sure the wells didn't leak didn't hold up, and all I did was smear it around the outsides of the wells. Pulling them off and gluing them back on with the same stuff would be asking for trouble.

And again, this was the same stuff that Demon Sizzler used. Don't remember the name of it, but found a post where he recommended it, tracked it down and put it on. All the wells did was seep and the stuff came apart.
