what size vacuum pipe? (Apexi boost solenoid)
 

I have bought a AVCR but it hasnt got any of the vacuum pipes with it. What size vacuum pipes will i need, from the boost solenoid and is it the map sensor? That looks smaller, any help please. Also where can i get some near Sheffield

Anyone

Either 3mm or 5mm internal diameter, and ebay is probably going to be cheapest for it.

Buy a couple of meters of both and cut to fit, the left over will come in handy at some point.
