Fuel tank coating

[rcnight]

Gents - Just picked up my new aluminum fuel tank. What coating are you/did you use and why?

I know this can be a touchy subject but this is the route I will be going with. It is probably not the best option if you are using a belly tank. https://www.yachtsurvey.com/fueltank.htm

I didn't use anything. I laid some 3/8" wide starboard strips down and installed the tank. Except for where the strips contact the tank, air can get around the rest of it. It will outlast me! BTW, when I replaced the floor, I moved the console forward so if the tank ever has to be removed, the console won't have to come out.

I'm with Boo! How long did the original tank last I assume foamed in? 3/8" X 4" wide starboard strips and let the air circulate.

Quick story, I had a friend who had a 24' T-Craft (I think that was the brand) which was the worst riding boat EVER built....period, we're coming in and I noticed there was a loud clunking noise which I thought was coming from something loose in the console. Asked him what it was and he said when the gas tank would get low it would bounce around in the hull! I thought he was pulling my leg, sure enough it was just laying in the bottom of the boat. He bragged it's nice and quiet when it's over half full. Never forget that!

Umm - so bare alum? Did you glue the strips to the floor or the tank? The other tanks I've done I coated with coal tar epoxy, then glued the strips to the tank. I would think gluing the strips to the floor/stringers with a bare tank might possibly let water in between. Over-thinking this?

Incidentally - got my tank from Ezell Industries in Perry. Great price and service.

I screwed them down. Got heavy with a couple screws, but it works.

My tank manufacturer used an epoxy coating, then I used the neoprene strip method between the deck and the bottom of the tank, making sure the strips did not trap water under the tank. Fastened the tank to the stringers with screws and plastic shim strips.

I have used coal tar epoxy (what most recommend) I have used standard 2 part epoxy for industrial water vessels and I have also installed them bare. Like mentioned mounting them where air can circulate around the tank is the best advice. No foam. Coatings help prolong but long as you don't foam them in they will last a long time.

Coal Tar Epoxy ($50) for enough to do 2 tanks. Heavy real rubber strips to elevate, protect tank and create air flow
