Gauge fitting?
« on: January 24, 2014, 11:52:50 am »
At the risk of ridicule and appearing like an idiot. How do you fit a boost gauge, specifically where do you run the vacuum hose from?
Thanks.

What you need to do is cut into the vacuum pipe that runs from the fuel pressure regulator and connects to a big pipe that takes a feed off the inlet manifold. There will be 2 connections, 1 is for the ecu the other is fuel regulator.

With the gauge you should get a t-piece, just cut the vacuum pipe (not ecu one) somewhere easy to get to. I cut into mine above the fuel rail. Ideally you wanna order a length of silicone pipe. I have some spare if your interested?

Then just run the pipe from the t-piece to the back of the gauge through the bulkhead. Assuming that this is a mechanical one? Will take some pics of mine so you get the idea.

Here is the vacuum pipe you need to put a t-piece into



Then like this



And then with the t-piece just feed that to you boost gauge or if its electronic you could do it like this
