how close?
My petrol tank (with fuel) sits in between the rear box section chassis and i can't get it out without taking off the body.
How close to the fuel tank can i weld brackets onto the chassis rails. I.e. not welding the tank itself but welding onto the rails around it - with a
MIG Clarke 151TE?
Thanks

Depends how much life insurance you have  Personally I wouldn't fancy it- seen the consequences....

Welding and petrol fumes don't mix!

I would suggest draining the tank and filling with water.
It's a pita, but a lot safer

how close are you calling close, risk is not always how close you are to the actual steel fabric of the tank (long as no pin holes in it) but how
close you are to vapour routes like, filler vents and outlets, mig sparks can travel a few feet in any direction if not shielded with same disastrous
results as if 6" away. its a caculation of risk, likelyhood and precautions.

The tank is about an inch clear of the frame and i want to weld some small brackets for brake pipes on the box section on the side away from the tank
- just dont want to take the body off and the tank out - unless this isnt too bad a job?
Thanks

Easy. Use rivets.

As said before. Its all about the vapour trail.
Empty tank (I wouldnt fill it with water) and extend any outlets away from the area. Do it in a ventilated area.
Oh and have a fire extinguisher on hand!
Goodluck

I cant see you'd have a problem to be honest if you aren't welding right by a fuel outlet. You have an inch between the tank and chassis
rail - so why not put a wooden board between the two as an insulating shield??

I was going to ask when you're going to do it, but since I'm in California, I figure I'll hear it go off...

I remember welding my brothers Alfasud near to the petrol tank when I was about 18.
We had the fuel filler disconnected to gain access, with my brother plugging the filler with damp cloths.
I finished the weld to see my bother chatting with a neighbour and flames coming out of the filler pipe!
Didn't blow up though

can you not drill and bolt / rivet/ rivnut/ clamp the brackets you need to fit instead for now until you ever have the body off.

This is what I intended to do, surely seen as secure enough.
