Now you have an excuse to drop the tank. :cheesy:What are all the tests I should do? I have check everything for vaccume leaks... With propane and starting fluid. Didn't find anything. Replaced evap purge valve and the gas cap. Still nothing. Cleaned all the possible sensors I could find with maf or electric parts cleaner. Nothing. Looked for any wire damage, nothing. Anything else? I filled my tank up today and my gas gauge quit working. I understand this is due to needing a new fuel level snsor. Would that cause that light?
