I recently purchased a 1986 Ponderosa 42 Sundeck and am confused by the 4 fuel ports on the deck: two on each side, one on the main deck at midship and the other on the step to the aft deck. When I added fuel through the lower port there was no apparent change in the fuel level in the sight tube; switching to the higher port produced an immediate increase in the fuel level. I assume these two ports feed into the same tank but don’t know why the level in the sight tube only reflected fuel added into the higher port. Can anyone explain what the two ports feed into?
