Petrol Tank

[MCTID]

I have said this before......I worked with a Welder some years ago who did 'Foreigners' for some years then stopped. I asked him why and he told me that he'd been working on a car Petrol tank which 'unfortunately' caught fire whilst he was welding underneath.

The car was a total loss, as was the garage he was working in and it was touch and go whether he lost his house....and his life - although he didn't. His Insurance didn't cover any of this as he hadn't declared he did 'Foreigners' at his home premises.....and it took him a long time to recover financially from this near disaster.

DO NOT take any chances working with Fuel Tanks.....empty them, clean them out and let them ventilate properly until you are 100% sure there are no residues or vapours left.

I don't want to pontificate, but in my field of Health and Safety, never let a good accident be wasted ! As in my friends case, let's all learn from it.

Be safe out there........the Corona Virus isn't the only thing that can kill you.

Old "out in field repair" trick to negate fuel tank volatility,  rubber pipe from car exhaust into tank for a few minutes after emptying to make it safe.

Replace fuel vapour with carbon monoxide.

Temporary,  get you home repair,  for a small hole,  used chewing gum is virtually impervious to fuel

Excellent, make do and mend.

Plastic Padding car repair paste is petrol proof and can be used for small tank repairs.

looking on the internet, I am amazed how few petrol tanks there are for sale and any I have found are so unbelievably expensive. 

I'm thinking of alternatives that will fit, 500t, 450t?, early 550.  Has anyone done this and are there any other models that will fit, or indeed from other manufacturers?

This has been a US thread for a while. Basicaly 500 and 550K 1971 to 1976 will fit but get the tap with it if its a later 550. 550 K3 but need sear as well plus seat hinge and lock mods.
Anything can be made to fit with time and patience but is it worth it

I had a 550K3 tank on my 500

The fittings all worked but there’s a gap to the seat.

So I fitted a 550K3 seat as well. The mounting points didn’t line up so a bit of hammering and bending was required.

I have a CB750K7 tank on my CB550F, not sure about seat fitting with it though as I have a CD175 seat on it too  , they all kinda fit, just not perfectly.
