Has anyone here replaced the fuel hose that goes from the filler neck to the tank on an early to mid 90s coach? I have owned over a half dozen built on GM chassis built by different coach builders and every one of them regardless of make has had a bulging dry rotted hose that looks terrible. Never had one leak but it's always been on my mind. They don't match up with what they were built on. Any idea what they used? Coach builder only?
