Fuel tanks

[Tx49]

I am probably going to go with a poly prefabbed tank. Are there any reputable brands other than Moeller. They are the only ones showing up in my searches. Also are there any prefab mfg's. of gunwale tanks. I would like to have a belly tank with a couple of gunwale "saddle" tanks gravity feeding down to it. I don't think I can get the 70-90 gallons I would like in a belly tank.

Inca is another manufacturer.  I picked up a 72 gallon Inca belly tank off ebay a month or so ago for a decent price.

Just don't expect any installation instructions from them     :x

Ain't that the truth!

As many tanks both poly and aluminum that have been replaced and installed here, I don't think an instruction manual is necessary.

that's what I was thinking.  I feel like I could do it with my eyes closed already.

Yeah, that's what one would think.  But look at Rick's rebuild thread.  The allowance for expansion and the use of neoprene on poly tank installations may not be obvious to all.  I think the information is available on this site now, but it sure would have been nice if we had some clear instructions from the vendors.  Inca won't even talk to you unless you are a boat manufacturer.

Ah, yes. But I bow to the vast cornocopia of knowledge acquired through great planning, great craftsmanship and sometimes great blunders by those great Aquasport seafarers who have boldly gone before me.

You can put a 85-90 gallon tank in the belly.  Measure the open space under the deck and call Phil at Alloy Metal Works.  He will fab you a new tank to match your dimensions and not charge and arm and leg - probably will cost less than 2 tanks and the associated plumbing.  Watch out for gunwale tanks - they move the CG way high - and feeding them to a belly tank takes some very careful plumbing and venting.

I think you are right about everuthing except the fuel capacity i can do. You have to remember that from the bow back 10' there is no room for underfloor tank. i will be lowering the floor up there for the cabin. I might be able to do 3 connected tanks under floor between the stringer from amidship back. I will try to sketch what I mean.

[love2fish]

you should get your floor pulled and figure out exactly how much room you're working with. I think you'll have more depth to work with so you could pick up some gallons there compared to a 22-2. also you could put narrower aux tanks on the outside of the 2 main stringers maybe,,, all running parallel up with the stringers.
