Hi,
I had a boost gauge installed by a diesel mechanic but, I think its in the wrong place.
Can anyone help?

I know that it should go on the intercooler pipe, but will this work ?
It works, but not how it should the gauge I have is a dual vacuum (left) gauge & boost (right side) The needle stays in the vacuum and never makes it into the positive (boost) it looks like it pulls a vacuum between gears and only make it to the middle of the gauge (zero) when foot is on the accelerator.
so it is always in the negative and when applying accelerator goes only to zero
Help do I need to get this refit or is it the gauge that needs to be reset

That picture looks like an actuating chamber to me and not a sensor at all.
Maybe the pressure to that is switched by an electric solenoid.
Just join up the line to make it original operation without the tee and find a spot just before the air enters the manifold.
There may be ports there which are far more suitable and actually reads the boost.
Having a dual gauge is fairly pointless as there will be hardly any vacuum created to ever read.
You did say, "fitted by a diesel mechanic" didn't you! Hmmmm.,

Hi
Ross,
I am thinking it's the fitting not the gauge and I need to know if it was was fitted wrong before I go marching in there demanding it redone. As It could be the gauge that needs to be reconfigured.

Can you squirt some compressed air into just the gauge? That should see if it goes above zero OK. Not too much pressure as the gauge will be lower rating than the compressor. Just to
check movement of the needle.
For a mechanic to fit such a gauge and then not
check if it works is somewhat negligent.
You can't reconfigure the gauge as such, but it's pressure feed line does, clearly, have to come from where turbo pressure will be/is.
Any mechanic should be able to achieve that.
