I need to replace the existing cap on my tank.The existing is an old pressure-relief lever type that has deteriorated. I looked at Zip, CC, etc. and they want an original style replacement (#307) cap for $35 approx. I am not re-storing the car for show, it's a driver, and it seems to me if I bought a cap with the recommended pressure rating, it would be acceptable to the system. Am I missing something( is it a special thread on the tank, or an unusual pressure rating, etc)? I haven't looked up the spec. but I believe it is about a 15 lb. system. Any knowledge on the subject to share with me? Thanx- lib
