Taiwanese trawler fuel tank

Probably still good to this day.With my luck the guy would be calling me a month after the sale. I have seen the "screw corrosion" thing you mentioned a few times, Even well sunk screws are a problem if the tank supports get wet. Another one of those things where you say "who'da thunk it ?".

I used a pedditt product called Splash of epoxy putty to seal all the pits after wire brushing, acid wash, acetone wash. Smarter people than I advised this. Then epoxy on the tanks.. I wonder if there is a semi flexable, paint on product to coat tanks with?

Seems there may be 2 ways to go. Ventilation or encapsulation. If no moisture or oxygen gets to the metal then no corrosion. I will never know, but I have been told (rightly or wrongly) that manufacturers are now coating their tanks as I did.

Greetings,
Mr. M. I think POR15 makes a 1 part fuel tank coating. As to it's flexibility...I have no idea but POR15 has GREAT products.

Thanks, hopefully I will never have to need it.

My black iron tanks did'nt last 40years. I pulled them out ten years ago and replaced w new aluminum. My water in tanks is almost non- existant because I pump a quart or so out of each tank every two months or so. I bend a 1/8th" copper tube to get to the lowest corner of each tank. I pour the fuel back in and the wTer out. Most all the time there's only 2 or so very small bubbles of water. I'm almost always supprised how little water is in there.

This is a reminder. I'm overdue for the little pumping session.
