Where to get fuel tanks???

What is the beneftit in powder coating CMP?

Chalk, it is an extra measure against corrosion. You know how bad un-anodized aluminum will corrode in salt air conditions. While most tanks are anodized, vibration can abrade this off pretty easily, so to protect against this and to protect the welded seams, it is a good idea to powder coat or epoxy paint them.

I did this for a buddy using two-part epoxy floor paint on a new tank, and it came out really well- sprayed it on in two really thick coats. Tough as nails. We then bedded the tank on rubber cushion and foam it in place. His old tank had some bad corrosion (unpainted).

What he said!

Timewalker; Just find the numbers the way Jacques does it. Measure the hole the tank goes in, then find one that fits!

[TimeWalker]

hehe yea but then I'd have to be to that stage so I could measure it

Then just calculate from the drawings, and make allowances for the glass laminations, allow some for the rubber mounting strips, fittings, lines, and some foam, and there there you have it.

BTW, Skyline tanks are not available directly but you can buy them from several stores. At the time of the design, they were available from WEST marine.

I have to ask, given a choice, what would be the best option: Alu or Rigid plastic?
Seems I have a few choices here, not sure what crevice corrosion is though...

personally i dont want fuel in plastic..... plastic expands and contracts too much to my liking and plastic tanks can absorb fuel.
i would go with a fiberglass tank before plastic.
my first choice is aluminum second fiberglass, and my third choice would be to stay on land. i dont care to be onboard a boat with permeated fuel tanks in the belly of it.

Just like there are Fords & Chevys, I disagree. If I couldn't have stainless, I would want plastic. There are many Coast Guard approved plastic tanks on the market. If there was a problem with fuel leakage due to the fuel permeating the plastic, I doubt they would be approved. Also, I have a 6 gal.plastic tank with my small outboard that is probably in the neighborhod of 20 to 25 years old and it has never leaked despite getting banged around in the boat. I believe fiberglass tanks are really Fiberglass Reinforced PLASTIC. However, if aluminum makes you comfortable, use it. I've seen too many aluminum tanks corrode or start leaking at the welded seams in a boat used in a saltwater environment to want one of them under the floor of my boat.
