I have just about completed my 73 atc70 project. Get a beautiful paint job and dent repair on the oem fuel tank. Then realize I am not able to get a seal with the gas cap due to the opening being warped. Tried different new caps with new gaskets and still leaks when gas sloshes around.
I am wondering if anyone has any thoughts about using a gas cap that screws on like some of the bikes use. If there was a screw on type that I could get to really tighten down perhaps it would seal?
I am open to any suggestions. I am including pics that can help explain the problem. Some of what you see is liquid steel in an attempt to build up the lip. Failed miserably. I also used a bearing puller to pull out how it is dipped in but not a fix. The lip itself looks like it is worn down.
Thanks for any help
