I have replaced the gas tank in my '55 Belair but there is a leak where the sending unit is. I have replaced the gasket and oriented it correctly but it still leaks. Is it possible to have a leak around the screw threads? If that's the case, what's the solution?

I had the exact same problem, ended up pulling everything out and used a new gasket and sealant around the gasket and screws. Mine was weeping around the screws. Seems to have solved the problem. I used seal-all, but there is some others out there, it's just all I could find here at home.

I used permatex #2 on the threads and it worked great.

The replament senders don't have the copper washers for the screws, these stop the thread leaks.

I second the cork gasket the rubber ones that come with the new tank are useless. I spent a year trying to get that crappy thing to seal to no avail. odered the cork on from a tri five member and no leak since!

Cork gasket and copper washers under the screws solved my leaking problems when I installed my new tank and sending unit.

I had the same problem with the junk restoration gasket. A friend of mine that is a retired HD truck mechanic took one look at my sender and sent me to the local IHC truck dealer. That style sender was used on trucks long after the 50s, the guy behind the counter took one look at it and asked how many I wanted.

Got the '55 back from the upholstery shop a couple of weeks ago and decided to put more than a few gallons of gas in since now I can enjoy driving the car with the new interior! Sure enough, I have a leak. My tank and sending unit are new last fall and I used a cork gasket and new screws with the copper washers. I didn't use any sealant on the gasket and used teflon tape on the threads of the screws. I was thinking that my next step should be to pull the screws one at a time and use some sealant this time instead of the tape. It seems that the leakage is from the screws and not the gasket. So, can I just use the black Permatex or what would be the best sealant that won't be affected by the gas?

there is a gentleman that has the connection for the rubberized cork gaskets for the sending unit,,if needed. if you do replace the gasket I would highly reccomend the rubberized cork.

His name is Greg Coleman and his email is [email protected] $6 per gasket and that included shipping at the time.

If you want, you can make your own gasket. I bought a roll of cork gasket material from O`reillys and made my own gasket. I also eliminated the clutch head screws and went with allen head screws instead, with no sealer on the threads. No leaks since that.

No Leaks!

O.K. The leak is fixed. I installed a new sending unit, cork gasket with #2 permatex sealer, and new clutch-head screws with copper washers and permatex thread sealer.
