I just noticed on the free side Dalej replaced the fuel sending unit on there 86XL. We ordered one earlier this week. Im pretty sure Ill have to pull the fresh water tank out of the rear bay to access the fuel tank from the rear. Dale, was this how you got at yours? Our fresh tank is so tight up against the front of that rear bay I cant tell by looking with a flashlight if that panel removes for access. Has anyone had this work done on there bus?
