    Default vaccum gauge going in soon, instal help?

    where do i tap into the vaccum line etc? ive allready got the wiring sorted its just the vaccume line that i need to know about, also will i need to get an extention of the tubing?

    also does having a vaccume gaue effect the performance at all? eg loss of vaccum?

    thanks in advance

    it wont effect performance at all as its sealed so it holds vacuam.tee into the vacuam line that comes off the manifold and goes into the firewall that goes to all the dash controls tee in close to the manifold as you can.

    Tap the gauge (using the tee-piece) inbetween the plenum and the one-way valve... its very squishy near the firewall.... but it is there!

    you can run the vacc line anyway you like... depends on length of the line you have... but take this in mind... the shorter the length, the crisper the response....

    na vacuum hose is usually pretty heat resistant, just run it somewhere not too close to your exhaust.

    See in this attached pic...

    THis is the vac line im talking about with the one way valve...

    If you want to check it youself... Start your car.... then after a few seconds... stop the car.

    If you then pull the hose off at the plenum, nothing will happen, but then, pull the check valve off, and it will suck air in the hose for a few seconds then stop. prooving its the vacuum hose.
