I'm heading over to the UK tomorrow to play in my 1984 Mercedes 307d motorhome. I have to replace the water pump on it when I get there but I know nobody on this forum knows anything about the pump on that model. However, it has dual fuel tanks and one has a leak in it. I assuming that epoxy will be a quick fix on that leak but I just want to pick your brains as to whether there is a better fix than that. I plan to clean it off well and put the expoxy on.

I've used a product called sloshing compound to seal leaks and rust inside of fuel tanks. I first found sloshing compound many years ago at airplane repair shops. In more recent times I've seen sloshing compound in auto parts stores. Sloshing compound works from the inside of the tank to seal, the epoxy you suggest using would be an outside repair. In my experience, I would rather use sloshing compound because it is specifically made for the repair you need to do.

Good Luck!
Tom

I have used epoxy for many tractor fuel tank repairs...none have failed , and some are 15 years old... I always use the epoxy to hold brass sheet to the outside and make sure I have lots of extra sq inches of coverage.... be sure it is physically and chemically clean, and do not squish the epoxy too thin when 'clamping ' up the cover to it...1/4 inch is thin enough.... and of course with epoxy be sure to follow the directions on the container with regard to proportions and amount of mixing.... I use JBWeld myself....
The slosh works well , but implies in my view having the tank out and able to be rotated in all directions...in addition to having to protect the openings which need to be open after you have sealed it up....On a motorcycle tank putting a stick in the exit hole was fine.. but on my subaru the pick up tube was two feet long and bent to where I could not protect the pickup end...and of course cleanliness is also an issue with the slosh...as is drying it after many rinses...
