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.
