ok mike, well ive been speaking to different guys about it today one person says one thing then another the next. Went to my local DIY/builders merchant's today to see if they had any of those bits they had nothing. Tried ebay mate and think i found a gauge that will do the job but not completely sure if its for what i need m/f connectors will be easy to get hold off can't find a T junction or compressed air fittings. Really want to build my own as i think £60 plus vat and delivery is abit on the exspensive side and looks simple enough to knock together your own when i find all the bits.
I think i will just listen to you mike as you seem to know what your talking about lol
cheers
matt
