So, I bought a 28' bowpicker last year. The boat used to have twin 350's in it and it was converted to a single diesel engine. The boat has two fuel tanks, but during the re-power, the front tank was disconnected... I believe it was around 1999 or 2000. Since then, only the rear tank has been used.
I removed the reel, and levelwind for more deck space and I noticed I threw the weight balance WAY off by doing so. The boat is pretty heavy in the stern now, so I'm looking at shifting my 100 gallons to the forward tank.
In order to do this, I have to re route the fuel line from the tank and plumb a return line either back to the tank, or use a t-fitting and pipe it back into the supply line. That's the easy part.
My question is basically, what are your experiences with older fuel tanks. The boat was built in 90, the tank was last used for gasoline, and hasn't been used at all for about 7 years. How did you clean the tank, or did you? Anything that you ran into in the past doing a project like this? Tips or anything else to consider are very appreciated.
