Just installed new fuel tank and believe the best solution to a leak free system is 2 things.

1. IMO new tanks are not compatible with old filler pipes and best solution is to replace the filler pipe also. I tried the oversize 0 ring and it was better but some seepage. The new filler pipe was a snug fit and leak free.
2. As previous owners have stated to get a leak free fuel sender you need the cork gasket, copper washers and aviation sealer.

I've had not issues in my 56 or 57. OEM cork gasket, clutch bolts, and copper washers are all that's need. No goo required.

it's the same tank for almost 30 years

I've put new tanks in about a dozen trifive's in in the last few years and always used the original filler neck, never a problem.

That's great but when I called the tank supplier he sent me the oversize O ring, so I cant be the only one with that issue. Any way I now have a very nice clean filler pipe.

Many filler tubes are rusted, inside. As were my last 2. Scrap bin, for both.
