Some say that you should set fire to a fuel tank before welding it.

I suppose it makes some sense - the explosion will only happen if vapour exists - a pool of fuel generally burns rather smokily and with a yellow flame indicating plenty of carbon and not enough oxygen.  So if the vapour has already been burned the risk of explosion goes.

Um - yes - something best left to the originator of the theory.

I was shown many years ago a method for welding a fuel tank. Run the exhaust of a car into it for 20 minutes or so. That was when using oxy-acetylene.

These days I use a y-piece on the CO2 pipe for the welder, and flood the tank with that. Never had a problem.

Probably best to use diesel Jerry cans.

I used to remove filling station petrol tanks as part of my job. We used to fill them with water, then pump them out and get a specialist to go inside and scrub the walls. We then had to get them out of the ground and cut up with oxy acetylene within 24 hours before the vapour came back out of the tank walls.
The first cut was around the filler. The tank was turned with the filler towards a blast wall so that if the tank did blow, the only guy killed was the one with the gas axe!

... and did anyone get killed ?

That's similar to what I learnt to do after after my hearing returned...
(The event described in my previous post was more than 37 years ago when I was young and stupid rather than now when I am old and stupid  )

Nowadays, I give the fuel containers a really good clean with hot water and detergent, then fill it with CO2 whilst drilling/welding/braising/soldering.
Out of date CO2 fire extinguishers have their uses.

Slightly OT, but I do recall a story told to me by a local fireman. He was called out to a fire at a very prestigious branded car dealership's workshop which had just gone up in flames quite spectacularly. Turned out that somebody had spilt some petrol on the workshop floor when removing a fuel tank. They then tried to suck it up with a vacuum cleaner. The result was carnage and it's a miracle that nobody was seriously injured. Anybody who thinks the Darwin Awards aren't relevant may wish to think again...

Fuel tanks at work were steamed for 24 hrs before they could be disposed of and I know the local radiator / tank repairers does the same before working on them

That's quite the kitchen! I never saw the show, so a couple of questions; Why the tall spare tire holder on the bonnet? What is the pull switch mounted on the dash? Does the jerry can mounted on the front have a hinge on it's side?

To me it looks like a push button pump for screen washing. Very common on British cars in the 60s and 70s.

 i have the dvd, and he did some squirrels with the jerry can.lifted off the can and grill. the grill was hinged,
wood was used in the jerry can to cook the meat when it was burnt to ash.

I like the upturned boat, I must have missed that series...

To use a phase much overused by Henry Cole on telly that HFW Landy is good from afar but far from good. It was at Bicester Heritage a couple of months back, I believe its for sale for £35k. I wouldn't give you £5k for it.

Somewhat OT, but I agree. How can it be a 1982 car with a galvanised chassis, 2/2A bulkhead etc etc.? How can the front lights be legal? Seems to be a very late registration for an ex MOD one if that's the explanation.

Scarily overoptimistic on price in my opinion.
