The inside threads of the
fuel deck-fill (aluminum) on my
boat has corroded, such that the fill cap is almost impossible to take off. After a bit of effort I managed to take out the deck-fill, assuming that it's a standard size and can be easily replaced. To my surprise, it has OD of 1-3/4" (i.e for a
fuel hose of 1-3/4" ID). It seems 1.5" is the standard and I have not been able to find a 1-3/4" at all. Any suggestions? I am thinking
buying a standard size deck-fill and then wield a 1-3/4" pipe to make it fit with the existing hose, but putting a barb on the extension pipe may be difficult.
