Cured epoxy is impervious to fuel. The easiest way to make a tank is to hotwire or carve a plug from expanded poly styrene foam, cover it with fiberglass and epoxy, when it has fully cured, cut the filler hole in it with a hole saw and pour some fuel in. This will melt the styrene. Wash it out several times with fresh fuel then fit your fuel line fittings. If you need to fit baffles, cut the tank in half, fabricate your baffles and bond the halves back together with fiberglass tape.

I had several reports lately that my web site is not working. I don’t know why as it always works for me when I check it

Resin that is really impervious to fuels, including auto fuel with ethanol is vinylester. Unfortunately, that means that you can not build over styrene foam, but there are other ways. This subject has already been talked over pretty good, so search on fuel tanks in the composite forum, and then come back with any more questions or join one of the threads already started...

Worked fine for me too.

Cured epoxy is impervious to fuel.

Incorrect - epoxies in the presence of fuel type liquids tend to soften over time and down the road will deteriorate to the point of losing structural integrity. Only Vinylester is impervious to fuels, including alcohol.

Mine is 15 years old. Made of glass cloth and polyester resin. Still hard and tight. It was made of 1/4" hardware cloth (that's the galvanized screen used for attic vents and so on, available in various grid sizes) cut to shape and wired together, then glassed over. Fitting are steel sheet woth whatever you need brazed to them, sanded or bead-blasted so the resin will hold them.

Gotta watch the layers. "Just one more to make sure" makes a really heavy tank. Mine's that way. Maybe that's why it doesn't leak yet...

Here's a device made of hardware cloth. It's a trap of some sort, not a tank, but you get the idea:

there are many different methods, as discussed many times on here including foam sandwich construction which is very easy to do with epoxy resin, foam and glass, followed by a fuel tank sealant like "Pro-Seal"...

 

[Lucjon]

I would use Epoxy, Divinycell foam, BID glass, and pro seal to complete....

Website works for me, though there are some pictures missing, like for the critical steps in making the landing gear spring. Love the site otherwise.
