sealing a fuel line

Ok this might be an odd question but here it goes. I put a sump in my factory tank that I have externally plumbed. I am using the factory float set up ( OBTW it is a 67 fairlane) for my fuel level guage and I was wondering what is the best way to seal the factory line leaving the fuel tank ( I think it is 5/16") I am thinking maybe squirting a bunch of epoxy inside the line but I don't want the fuel to eat through it and start to leak.
Thanks in advance.

sod-er it

Is it in the front or the top? A cheap fix would be to put a very slight flare on it and slip some 5/16 fuel line over it with a bolt or plug in it. Couple hose clamps and you are done. A good more expensive fix would be to flare it and cap it. Should be able to find something in brass or AN. It will just cost more.

I tried capping it but it is a pump gas deal so the fuel has ethanol and it started to eat through the rubber cap I put on it, BTW the sending unit is in the front.

I was thinking more the lines of a nut on the tubing then flare it. Then you could use a plug to seal it like you would with a brake line..

Dave,

Is the float assembly still in the tank? If you take it out of the tank and bring it down we can pinch it together and solder or weld it, or completely remove the pickup tube and plug the hole in the plate. By removing the pickup tube, your car will be lighter too.

Or if you want to weld it yourself in the tank, it will only go BOOM once. But I want to get it on tape it in case you end up looking like this guy!

Rick,
I will pass on the "welding in place idea"
