I'll get some pics of my setup tomorrow for you. The BPV can come off the front of the plenum, the fuel reg I picked up with aT piece in the line to the fuel tank vapour trap release.
When tuning we found that sharing the line to the vapour release and/or the BPV causes fluctuations In the pressure this makes it a pain to tune, I suffered because I have a Haltech and it has it's own sensor built in, if your going up rev I don't think it will matter but you may get a flick in the boost gauge.
Worm gear or "jubilee" clips eBay will have, I get mine from a local supplier he has everything from about 6mm to 100mm I can post ya some if your really stuck.
