Can any one confirm if I need a brake pipe flaring tool to flare the ends of the 6mm gas pipe from the tank to the vapouriser?
I am going to be fitting a second hand kit from a 535i E34 to my 325i E30 over the next few days and using new copper pipe. I have obtained the pipe and just ordered a set of new olives and nuts from the bay of e and also some 'Gas Tite' non hardening joint sealant.
I have read all the LPG fitting threads but there is no mention of flaring the pipe by anyone?!?! Any advice Gratefully accepted!

Thanks in Advance :D

There are two different types of compression join used with copper tube - flared joints and compression joints using olives. Theoretically only flared joints should be used with soft copper tube, but olives are OK in practice.
If you are using olives, then the pipe won't need flaring.

Excellent! Thanks Brian!! I was a little unsure as the old pipe has an olive one end, male (the vapouriser valve end) and its a flare inside a female thread at the tank end.
