Extreme Veteran Posts: 303 Location: Harrisburg, Penna | Hi Jim, I just had my gas tank totally cleaned and coated, somehow the outlet tube got bent and when they tried to straighten it, it broke. I am now being told that the gas outlet tube has a totally different thread with a rounded edge and no one seems to know how to remake it. I been to dealers, garages, hydraulic hose makers, machined shops, no one ever saw a connection like this. There is a bolt welded right on to the tank, this piece is where the outlet screw need screwed into it. Do you have any idea what can be done with this broken piece. The sleeve with the treads can be used over but no one knows what kind of flare end it has.? Would 57 or 58 Mopar Plymouth or Dodge have a similar setup I could use?

Extreme Veteran Posts: 406 Location: Hilltown, PA | I've dealt with plenty of seized tubing nuts over the years and I have to disagree with the thinking this was cut - to me it appears exactly like a twisted/torn tube due to a seized nut. As far as the fitting/tube repair I'm assuming this is a standard size tube and nut/thread. While the flare is a bit unusual you should be able to reproduce it with a standard flaring kit. Most U.S. vehicles use a standard double flare in a V configuration. The tool which does that can be used to duplicate what you have by partially performing the first part of the flaring operation, creating a "bubble" type flare. You'll want to re-use the tubing nut you have to retain the deep collar below the thread, although these are available. I'd also take a good look at the seat and make sure it isn't supposed to be a double flare, and that this particular tube was somehow incorrectly flared, and managed to function because there is no pressure on the fluid at that point.

Gregg Looks like it was twisted off to me. I've used 5/16 brake line either store bought or flared by myself a standard brake line double flare and never had a problem. | ||

Gregg if the fitting was seized theres no way to turn/twist it off. what you mean is the tube was seized to the fitting and in that case the angle of the bend wouldn't be close to 90°, like in this case anyway, what i meant is it was done deliberately. in order to twist it off you have to repeat the twisting motion several times. no way you separate a line completely by accident. | ||

Expert Posts: 2196 Location: Muskego, WI | Ron, I hate to say it, but I've live through the exact situation with my '56 Imperial. Same odd flare that I could not duplicate and make leak free. Dorsey is right about coatings, such as gas tank Renu, they do not work long term, only a few years at best. Do yourself a favor and purchase a good used tank, find a new one, or have one made. I had a new one made with up to date, readily available fittings (AN fittings). | ||
