While I have the rear axle out of my 1937 car, I thought I'd remove the gas tank to check and clean it. I noticed that the fuel tank to fuel line was weeping. The fitting was tight. Seems that the fuel line was replaced at some time. The steel line itself did not hug the frame, had no hold downs, it just ran straight through the air. I also noticed that the fuel line to gas tank has a double flare ferrel, for some reason I think this is not right. Should the fuel line have a double flare ferrel? Or should this be a just a flared fitting? AND, shouldn't the fuel line hug the frame from back to front, with some kind of hold downs along the way? Thanks, Mike

The ferrule and nut are correct. The line should be held down in a few places along the inner frame rail. There is also a clamp (there should be) on the top of the rear cross-member. Two other clamps along the frame... each shares a bolt that attaches the running board (vertical) brace.

Thanks a million. I think that I will replace the fuel line and try to find where the original hold downs are. And route the line a lot closer to the inside of the frame. Mike

I am weak on all things plumbing, so looking to others to help me get educated. Would a flared fitting have a ferrule? I thought a ferrule is used on compression fittings, the ferrule is what gets compressed and makes the seal. And a flared fitting does not have a ferrule, the flared end of the pipe makes the seal. Is this incorrect? Am I missing something? Thanks.

Jay from Chicago, h*llo from Milwaukee. A single flare is applied to a pipe or line. It basically just turns the end of the pipe in to a thing that looks like a trumpet horn. This single flare gets squeezed between the pipe nut and the other fitting. They have special conical ends so the flare can be squeezed and become sealed. A ferrule is a small brass conical sleeve. It has a chamfer on each end. This ferrule is slipped over the pipe and is squeezed by the fittings, which are different than the single flare. Hope that helps. Anyway I see that my ferrule on the gas line is damaged. This is why it was weeping. I found the hold downs they are not holding the gas line. I will replace the entire line. This is always a tricky operation, trying to use one continuous line and get it routed properly. Thanks, Mike

Ragtop, actually that was the 1st project I did when I first got the car. The car would run for a day or so, then would stop. Turns out that the carb, sediment bowl and fuel pump would be clogged with what looked like spaghetti. Apparently, the previous owner must have used a sealer that was not very good or didn't prepare the tank properly, some thing. The sealer was pealing off the tank and the fuel pump would suck it up. At that time I removed the tank and cleaned it inside and out, blow out the fuel line, cleaned the fuel pump, sediment bowl and carb. Quite a job, but it solved the stopping. Mike

The previous owner probably used silicone sealer on fitting and possibly the sending unit gasket. Silicone around gasoline is a big "no no". That's what caused the "spaghetti".
