I'm in the process of removing the original fuel tanks from my 31 Commander. I know there's a few here that have done it or had it done and wonder what size tanks you replaced them with.
I plan on having new aluminum tanks built, Looks like I can get a tank that's about 22in high, by 22-24in wide by 40in long at the bottom and 46in long at the top in there if I pull the exhaust off the engines in the center of the boat. That should give me about 85-95 gallons/side.
Any insight/ tips? I've done this once already on my Catalina, but just had the stock tank reproduced.
My tanks don’t stick out under the hatch. I would move the sending unit though, I would move it out to the filler side. It would be accessible there. The pickups are accessible from the front, I put them there for 2 reasons, 1 accessibility, 2 sort of acts as a reserve. In the case I should run out of fuel on plane the angle should leave fuel to use as the boat levels out off plane. I don’t ever plan on testing that theory though.

That tank looks great. The only thing that I would change is to move the pick-up and gauges so that they can be accessed by the lazarette hatch. I was having a problem with the starboard engine stalling out over 2,000 RPMs. I switched over to the other tank and it ran fine. I removed the valve and found a wasp stuck at the choke point in the valve letting some fuel for low speed but not enough for planing speed. I used composite mufflers (can't remember what brand) but hose sizes were the same. The weight difference is tremendous. The shipping weight for the new mufflers was 11lbs. I believe the cast iron originals weigh about 50lbs each. Dave
