Bill-OC24 Posted July 24 Report Share Posted July 24 Hello, I am finishing up interior glass reinforcements and tabbing on Hull # 8 and would like to know what fuel tanks are being used or recommended? I would like to use a two tank configuration, and I suppose I would prefer plastic. To be honest, my ignorance of fuel systems is pretty impressive! Thanks for any and all input, Bill Greenwood, SC Quote Link to comment Share on other sites More sharing options...
Reacher Posted July 27 Report Share Posted July 27 Bill, 25 years ago I built a 22' okoume panels on mahogany frames sterndrive motorboat based on plans. I'm not sure if that's a valid comparison or not, but FWIW I still have it and use it. I installed two 18 gallon plastic tanks and have not encountered any problems. They are mounted amidship for weight distribution. Two tanks fit better than one large one. I liked the idea of separate tanks in case I got bad gas in one, but that hasn't happened. Each is wired for fuel gauge and grounded. They are plumbed to a manual three way valve, left, right, off. I have a single fuel gauge in the dash with a switch for left tank or right tank. The only inconvenience is that the fill tubes are located on opposite sides of the boat. Sometimes the hose reaches both and sometimes I have to jockey the boat around. Good luck with your build.

Bill-OC24 Posted July 31 Author Report Share Posted July 31 Thanks so much. I have found the right size Moeller tanks, a 40 gallon in front of a 38. Reportedly 6 - 8 week back order but no worries as I am still doing all the tabbing and below deck fiberglassing (a drag). Trying to convince myself painting the bilge would be a good thing, but unclear why given it will be an outboard and all the bilge spaces will never see daylight.

Oyster Posted August 1 Report Share Posted August 1 I am not really a fan of plastic tanks. I use aluminum tanks from RDS and always coat them with either Coal Tar Epoxy or Interprotect 2000 barrier coat . Once you install a tank below deck, you may need to tear up a bunch of stuff to change out the tank when you get some smell or leaks. Plastic tanks, unless they have changed have fuel gauges installed in them. And overtime, even if you do not get any smell that wicks thru the plastic, with expansion and contraction the screws have a way of working free and gas leaks from around the threads. [just my observation, even in production fiberglass boats with plastic tanks below decks too. ] There are outlets that custom build just about any size or shape, of course with some lead time.
