Re: pulled up the deck..

as long as the new tank is below deck height with the fittings.....you are good.

just make sure there is clearance for the sender and input hoses.

Thanks oops. you are the man!

Re: pulled up the deck..

This seems like a good place to drop this installation of an aluminum fuel tank.

On an alternate note, I think it's USCG regs that dictate material construction & compliance w/ the new, as of 1/2012, EPA regs:

Have a good end to the week tomorrow.........

Re: pulled up the deck..

oh, wow. My tank had a lot less. a tube to fill it up, a tube to the engine and a tube to vent. A gas sensor and a ground. Thats it. Since my boat is old enough to have been in the revolutionary war, does it still need to comply with those standards?

Would switching to a urethane tank yield any benefits or is it a bad idea?

Re: pulled up the deck..

I mostly left it for reference about why tanks are so expensive, and tough to DIY. Moeller makes a lot of tanks, go to their site & find 1 that suits your needs for size (LxWxH), shape & capacity, then find a vendor & price you like. iBoats carries many of their tanks.. Other makers may also offer a wide variety of poly tanks....I 'think' those new EPA regs apply to OEM boat builders, else you wouldn't be able to still buy anything that doesn't include the evap loop...

Re: pulled up the deck..

depending on how much modification you are willing to do, you can make things work...I did not want to deal with a portable 6 gallon tank that my boat had so figured while I had a chance during the rebuild I added a 24 gallon tank...had to do a lot of modifications...the tank started around this post on my thread

when changing locations of stuff you have to be mindful of weight distribution, because of the increased fuel capacity in the rear, I had to move battery locations closer to the front..its all about what your willing or capable of doing

Re: pulled up the deck..

Nice. you put some work into that!

SO I decided to get a gas tank that would fit into the space already created. I will get a Crosslink Polyethylene constructed tank.

I did the calculations and my boat had a 35 gallon tank. Would there be a problem of making it 45 or even 55 gallons if its in the exact same space? It's pretty much dead center of the boat so it wouldnt cause any weight distribution problems.

the only problem would be weight. at 6.2 lbs/gallon I would be adding 62 or 124 pounds to the boat load. a 19 foot trihull I'm sure could handle that no problem. Anybody see any flaws in my thinking?

Re: pulled up the deck..

I don't know enough about your boats specifics about adding a 1/3rd more fuel & weight, so I won't comment on that. I will say that the extra weight (124lbs) is about the same as most average sized teenagers...... But this might be helpful when you install whatever tank you decide on. Note: foam is not a suitable isolation material.......

The fuel cell drawing I posted also shows an anti-siphon valve if the fuel tanks output is higher then the motors input, which you asked earlier about raising & lowering the tank. As well as using USCG approved fill, vent & to the motor fuel lines.
