The tank looks better for a clean-up. They were a pain to make, but they were the only ones on the market at the time. They were all tested for leaks before they left me, even if the welding wasn't pretty.FraH2O wrote:I bought (my father) 2 of these about 20 years ago from GB.Knowledge wrote:The petrol tank looks very familiar.

Great infos, but your tank is still perfect fron 17 years ago. No one leak, no problem....just a little lifting, but always tested and run good!Knowledge wrote:The tank looks better for a clean-up.

If you want to retest the tank for leaks (ideally before painting) then fit the petrol tap and turn it off. Then cut around the valve of an old inner tube from a tyre and fix this over the filler hole of the petrol tank using a jubilee clip. Next use a pump to put a bit of air into the tank, and use a paint brush to apply a mixture of water and domestic detergent around the joins. If you see bubbles (and they can be tiny bubbles) then the tank has a leak.
I hope others find this information useful.
