YES I had the same problem and bought a new original type shut off valve .That lasted less than a year so I bought another one and it developed the same problem ! My wife can smell the slightest gas smell in the garage . I found on the forum where one guy suggested getting a ball type shut off valve .SO I went to my friendly hardware store and he had a small ball valve with the same threads I bought that it was half the price of the
"original type "
the small ball valve has been in there now over a year with no problems .
To install it I had to bend the fuel line just a little to get the threads to line up.
you may need an adapter too I don't remember if I have an adapter on it . If your like me and do not have a high point show car this works great .
