I have a 3B 65 with the 640594 on it will the chrome fit? ( no leaking ) how about locking?

Willys Tech:
Yes these are interchangeable. Either will work. They dont make a locking gas cap for these vehicles.

My current cap measures 1.75 between tangs. Believe 2 is required or it slides around on the tank and seems to leak. Could you get that distance before i order? Thanks

Willys Tech:
Yes these are 2 between outside tangs or tabs just like original. The overall diameter of the cap is: 2-3/4 just like original.

Does this cap have a rubber seal so does not leak? My original cap leaks when jeep is tipped to that side.

Willys Tech:
Yes it will have the seal so it doesnt leak out.

Is this gas cap the same measurements as original?

Willys Tech:
Yes they will fit just like original.
