I have had the gross evap leak for a long while now. It will sometimes go away when it gets really cold here. I also have an issue filling up were the gas pump thinks I am full and I have to stop and wait a second to continue filling up. I have no idea if these two issues are related but I have been looking over the rave manual well more specifically the diagram "Fuel tank and breather components". I was thinking about replacing the filler tube to correct issue 2 and pray it helps issue 1. I was curious though if the "relief valve" and "vent to EVAP canister" need to be changed at the same time. Is it hard to disconect those? Do they ever break when swapping out the tube? Any reason to think they have anything to do with either of the two issues I mentioned?
