1952 Chrysler fuel tank

[nickg112]

I have a 1952 Town and Country. The fuel line that goes to the tank broke. The old fitting is jammed and I cannot get it out. I want to try drilling it out but want to have a new fitting before I start. Does anyone know where to get one of these fittings? My understanding is the flair is different from a common flair (double bubble). The 1st photo below shows the broken line on my car. The second photo labeled 53 tank is a photo I found on the internet. This is not my car but shows how the inside looks and where the flair seats. I believe the thread size is a 1/2 inch and is just a standard thread ( not a tapered pipe tap). That is why a flair seats on the bottom and the actual threads do not seal the fuel. The flair does the work.

I tried an easy out on my tank and no luck on moving the fitting.

 

I just added a 3rd photo. This is the part that I think I need.

 

If I cannot get the correct fitting and flair, my next step is to cut the tank and weld a new fuel tank bung that will have a tapered pipe tap hole for sealing fuel.

 

Any ideas or thought appreciated.

I had the same problem on a 52 New Yorker sedan. It seems to me it was a standard type of flare fitting like a brake line but maybe a single flare. I couldn't get mine to seal and did not want to over tighten it, so I put in a red fibre washer left over from an old carb kit and it sealed perfectly.

 

Yours looks funny as if someone hit it with a tapered reamer. You could try making a bubble flare by upsetting the tube end with a brake flaring tool then don't do the last step. Or use a European brake line with a bubble flare.

It is a special fitting.

There was a discussion about it a couple of years ago.

I needed one for my 48 and found one for sale from info in that thread.

I am not good at finding past discussions, but I am sure its there someplace.

That picture of the internal tank fitting was a picture I posted on another website and yes the tube nut is a special long tube nut. The tube end is a special bubble flare backed up with a flared.copper sealing washer. I posted pictures of all that. I will post them again if needed when back.

Only up to 1948 do the mopars use that brass filler crush fitting sealing the outer fuel line to the inner tank pick up tube.
