Hole in fuel tank :(

[anonymous-user]

Got a call from my TVR dealer today, apparently a fuel leak I had in the boot is not due to leaky pipes but a hole in the tank itself.

A new tank is about £300 but they seem to think to have it welded would be about £80, which they will get done.

Is it a common thing to go on these, bearing in mind the car is only just over 5 years old ??

Welding a petrol tank - not a good idea to try yourself at home

Haven't heard of one going before now.

Welding at home is OK as long as you understand the chemistry It's the vapours that ignite (flash, not burn), so if youve got an empty tank with a trace of fuel it can go up with a rather large bang

The trick is to flush it out, but leave it full of water, the very small amount of air left in the tank makes for much smaller explosions

I have had someone explain that it's OK weld a tank when it's full of petrol The logic being that as long as there isn't any air you can't get a fire etc. I shan't be trying that

It's o.k I'm not doing it, especially after my lack of welding skills when I was on a Ford apprenticeship.

The instructor said, I'll pass you, but if anyone asks if there is someone that can weld, don't put your hand up.

That was Arc welding though.

Castle TVR are arranging to get this done as the tank is alloy, and there aren't many people around that weld alloy, fewer still that will weld a petrol tank.

They are going to line between the bodywork and the tank to ensure they do not rub.

Hopefully pick it up saturday.
