Morning!

The fuel tank on my 1988 90 has sprung a leak. I cant see where from exactly but I imagine it is from the seam. Is it repairable? If so does anybody have any tips?

Thanks

Petrol or Diesel. How much of a leak can be debatable but stick a small tupperware box underneath and refill.

Check the seals on the top of the tank for the fuel sender and feed.

Out with the old and in with the new if it is the seam.

Thanks for replies, its a diesel, not from sender or lines, almost definitely seam so looks like a new tank then, bugger!

as per @Gmacz never worth repairing for the cost of a new one!

I plugged a leaking petrol tank with David's Isopon years ago. It was meant as a temporary fix until I could afford a new tank but it lasted for a couple of years until I eventually scrapped it due to gearbox rot almost everywhere.

I don't know why I typed gearbox in that last post, I was thinking of two different things at the same time, very dangerous thing for a man to do.

I might have to go down that route for a while, they are £100! I could get away with a temporary fix on a tank but not on tyres.

If isopon rots your gearbox, I think I would just spend the £100 for a new tank.
Problem with the seam is finding the hole and diesel sticks around while petrol evaporates. The sealant will have trouble sticking.

Yeah, I did think of that, I thought I could clean off around the seam with a blow torch.... then I remembered setting fire to my motorbike and my garage trying something stupid like that before so I just bit the bullet and ordered one
