    Connecting the vaccum lines

    Quick question for you all

    i was recently told that ideally VEMS should be using a dedicated vaccum line to see vaccum and boost without any T-pieces interference if possible OR if there are going to be any, it would only be for a boost gauge and nothing more.(that is because the map sensor is static and other devices such as the dump valves require flow to work with and may produce lag... or at least that is what i understood)

    Anyway, question is, at the back of the wagner manifold i have 4 nipples to connect to various areas that need the vaccum. I would like your suggestion as to where i can connect T pieces to manage to connect everything in, without needing to drill more holes on the manifold!

    I have to connect:

    1) FPR
    2) ECU map sensor
    3) PCV
    4) Small line that goes through a one way valve to the pink plastic line ( think this one is for the AC and diff)
    5) 2x Dump valves
    6) Water injection

    Currently i have: 1 line for FPR, 1 for Map sensor, 1 for PCV and then i use the 4th one with 3 T pieces to connect the rest.

    Is it a good idea to try and break down the 1 line that connects so many things, into 2 and utilise the vaccum line that goes to the PCV to split the rest of the devices? Or it doesnt make a difference..?

    thanks
Working...
