ollski said:I personally would say forget it expensive, nasty fumes etc. Why not buy a bunging kit, presuming you are on an open vented system, re-usable again and again for those simple jobs like a single rad valve.
So I'm guessing the way this works, it create an airlock ????ollski said:A bunging kit is simply 2 rubber bungs, 1 seals the feed from your f&e tank, it is cone shaped at one end and just pushes in until it seals. The other on pushes either into or over your vent pipe. Providing these make a tight seal you can then remove a component anywhere in that system which, as long as you only have 2 open ends, will hold.
