Another good spot would be straight off the intake manifold. The port on the left is for the powerbrakes, the one on the right has a reduced diameter. Might be okay, but the middle is a full size connection. Just put a T in there and run with it.

The mounting was in an unused spot in the console. Bezel broke the other day, so need to find a new one.. This gauge doesn't have numbers, but if you drive it for awhile it will still give you good driving knowledge. I should probably calibrate it one of these days using my tune-up vacuum gauge, but this works fine.

Well I have spliced my gauge in where you suggested and it does not work properly only reading 3 or 4 at the most.

This is the gauge :-

52mm Auto Smoke Vacuum Pressure Dial Gauge Meter Silver on eBay, also Dial, Dash Switch Custom'n, Interior Styling, Car Tuning Styling, Cars, Parts Vehicles (end time 28-Jul-08 14:00:54 BST)

Before I got around to fitting the gauge this happened.

My wife used the car yesterday and it did not run after starting , being doing that a bit of late , so she hit the throttle to try and catch it and I heard a bang under the bonnet but the car ran so I let her go out in it.
When this happened last time it blew the big rubber donut off that is between the manifold and the air-fuel control unit and it refused to start till I reconnected it.

When coming to splice the vacuum line into the middle pipe connector in your photo I found that the other end under the manifold was not in it's housing ? [ caused by yesterdays bang ? ] the flame trap for the PCV and yet the car could start and run ? strange ?

It took me ages to get that back in but finally did it and spliced in the t piece.

When the gauge did not work I though the pipe was blocked down to the flame trap but it is clear , if I unscrew the middle pipe connector in your photo the car will not start and yet it could with the other end of the pipe hanging in the air ? the only difference being the screw in part has a restrictor at the manifold end ? lot smaller than the pipe diameter.

I do not have the third pipe in your picture on the right I have what looks like a bolt in there so I am going to see if it is tapped all the way through and I can get a pipe adapter to screw into it.
