Where To Tap Vac Line For Boost Gauge?
#1
![Default](/forum/images/icons/icon1.gif)
Going to be installing a boost gauge into my XJR and was wondering where the best place is to tap for the vac line? On a few of my older turbo cars, I ran directly off of the intake manifold or fuel pressure solenoid, where available. Not 100% sure where I should tap on this vehicle though.

But I modified my drivers side defrost vent to hold the boost gauge and it looks fairly stock after I painted it.

Completed the install of the boost gauge. There is a PERFECT spot to tap the vac line. It was mentioned in a previous thread that there is a vac line coming off of the "V8 cover" and it is right there on the passengers side. I traced that line and it actually has a T fitting on it. That T fitting goes to the FPR and then the other side actually has a vac cap on it. I removed the cap and put the tubing that came with the boost gauge there. The rest was a matter of routing the line, all the wiring to the gauge and finding a 12v key on source.
