Hi
the accessory vacuum lines come off of the back of the intake manifold. They are colored semi-rigid lines. Or there is the brake master cylinder vacuum. Do you want to put in a permanent gauge or measure vacuum?

Hi
as my machine is a little different (96)I can't say I immediately can identify a vacuum line from your picture.
Does your gauge come with any directions? Does it say to "splice" into and existing vacuum source? I suppose you could put it in line in the PCV line between the PCV valve and the intake.
Anyone want to jump in here? I have not installed a vacuum gauge, just measured vacuum a time or two.

The vaccum system is ALWAYS drawn off of the intake side of an engine. Follow that 1/2" hose coming from the can behind your brakes master cylinder to the intake manifold, for a likely spot to tie into.

Sorry, I may be a bit naieve, but why do you need a permanent vaccuum gauge? I thought this was a "turbocharger" type necessity.
