So I need to replace my fuel tank and it looks to be very expensive to replace with aluminum. My tank now is a195gal tank. And it has started leaking because of corrosion.
I looked and Moeller makes a150 gallon belly tank which will fit and I got to thinking why even use a aluminum tank if it is going to corrode and leak eventually. The plastic will never corrode.
So how would one install Moeller tank. Do you put it on a rubber pad? I assume you do not foam it in but how you keep it from moving if it is in a area larger than the tank. I have never installed this kind of tank, only aluminum. Can I block it in with foam blocks? What if it is not the same angle as the v angle as the tank that is in there. Can I use rubber mats to help it fit in the bottom.
Has anyone installed a Moeller in their boat. Are you happy with it.
Why doesn't every boat manufacture use a Moeller tank since aluminum tank eventually corrode. Am I missing something and I should be putting an aluminum tank back in the boat. BTW The 150 is like $600. Is that what an aluminum will cost.

Thanks for you help. It just seems like buying a Moeller is too easy.
Boat is 1995 Whaler Outrage 24
The limited offerings of Moeller's below deck tanks mean many don't have a plastic option. Are you sure the Moeller tank has the correct V angle?
For fitment, you can use rubber strips (angled to allow water to drain rearward) on the bottom. For the sides you can use foam and/or strips of a non-degrading material.
You may want to consider aluminum straps across the top, fastened into the fiberglass edge of the cavity to keep the tank from lifting up.
I would check with a local fabricator for a quote on aluminum. I would guess at least 1k.
I am not real familiar with with the third generation Outrages like you have, but I do know that now Boston Whaler has finally redesigned the fuel tank retrofit for the 2nd generation Outrage/Revenge/Guardian hulls. It does not use any foam at all, nor require foaming the tank in place, and supports the tank all around, and so any water that gets in can flow under it and out of the boat.
I understand this new fuel tank installation method is available from the Commercial Products Division, and still uses the Florida Marine Tanks aluminum tank. You might want to give CPD a call.
If memory serves me correctly, Whaler tried installing plastic tanks in the early Outrage 22 models, and it did not work out well.
