Different tank
Maybe the original tank was replaced, that was the case for my ODay 32 cause I think the stock tanks were steel or alum. and now I have a plastic tank that's in the place of the original and it's a lot smaller cause it would fit down the storage area with out taking half the boat apart,funny just yesterday I was looking this whole tank operation and was wondering if I could put a larger one so I can relace the cheap tank thats without a gauge.
