OT I know, but a friend of mine has found a gavanised fuel tank for his landrover, but there seems to be various accounts on the internet of the sulphur in diesel reacting badly with it. Does anyone on here have any experience?

Cheers

Many years ago all vauxhall fuel tanks were made from pre galvanised sheet steel. Any steel tank will need some protective coating inside otherwise it will rust through.

Where did that link come from!

Modern diesel and biodiesel have ethanol in which strips the zinc from galvanised pipes and so I would assume it would strip the galv from the inside of a fuel tank. This is a problem especially with modern fuel injectors as the zinc particles block them up very quickly, and at several hundred pounds each that'd not be a good plan.
A plain steel tank should be fine for diesel.

I was always told never to use galvanize where it would come int contact with diesel as it reacts to form zinc flakes. This was the old high sulphur diesel but if the modern fuels also attack it the problem has not gone so I would not use galv.
