installing a boost gauge.

[ll3lue]

hey i have a dual gauge apiller pod from autometer im going to install a 2 1/16 phantom boost gauge it goes to 30psi vac/ 30psi boost and i wanna know where is the best place on a 87 GN to tap the vac line???

i would search for this but the search feature doesn't seem to be working.

the vacume hose coming from the MAP sensor works, you can follow it by looking at the diagram on the vacum system in the engine bay

I would think the MAP line would be a good place to tap. There you have vaccum and boost, which is what you need.
