Is anyone willing to share either:
- a detailed procedure for purging automotive fuel tanks prior to welding,
or
- details of a firm who could carry out a clean and provide it back to me with paperwork proving it has been tested free of flammable atmospheres.
If it was something bigger I could probably borrow a gas detector from work, but we don't have anything with a long thin probe to get in there.
In case you're wondering why I want to do such a thing...
It's a sub-project of the Landy build, I want to add a threaded boss to the top of the tank, for a dip-pipe to act as a self-limiting secondary fuel draw-off to allow me to fit a (period appropriate) eberspacher "benzin" heater.
Given the high risk nature of the job, I figure that planning months in advance is probably the best approach here.
Depending how difficult/costly this is to do safely, both a secondary tank, or just tapping into the main fuel feed are alternatives with their own downsides, but reduced risk of explosions...
