I mentioned in the original post that I plan to dip the tank from the fill port on deck. There is very little clearance between the top of the tank and the salon deck, and it's really un-accessable from the ER. The PO put down a real nice hard wood floor in the salon. Unfortunately, he didn't have any access panels for the fuel quantity senders. I wonder, did the boat come with access panels from the factory? I'd hate to have to tear up the entire floor just to get to the senders. Hence, the dip stick solution.
