If you have trouble identifying the vac line for your new gauge to tap into, I'll kill you, skin you, and scalp you. Or post a pic for you. I took 3 under the hood of the boss'* car for that purpose today. Just follow the line from the FPR on the fuel rail up to the vacuum ports on the SC, and tie in somewhere in between with a T fitting. The lines are 4mm. The third branch on the T will have to be what your gauge came with for hose diameter.

So true.
I hooked the guage up to mom'* 93 Park Ultra and it showed 20 inches, but I just idled. No drive time.

I'm looking on e-bay tonight to see what there is to be had that would look right at home in the SLE SC.

I have an aftermarket boost guage on my 95 ssei, i teed in just before the boost control solenoid, with a t and some tubing, im pulling about 13pds of boost at wot, thats with cai, exhaust, smaller pulley, ill post some pics of the install if anybody is interested, i teed into a line when i first got the guage and the dash guage was jumping all over so i had to come up with another line to use, works great now, its interesting how the factory boost guage must hit zero before the aftermarket gauge even bounces at all. let me know if you need any help or pics.

Your reading is very wrong and you should move it, or you are running WAY too small of a pulley with a huge exhaust restriction, and are getting tons of KR.

The line near the FPR looks easy to tap into.... I will use that. I just need to find a place inside the car to mount it so it does'nt look too ghetto!!

You said you have some pics of the install on your boss'* car? I am sure I can figure it out, but it does'nt hurt to see how someone else does it.

I am suprised at how well it runs now, from 65 mph it pulls real hard.

Here is my fresh air scoop that helps supply air for mainly highway driving. The other pic is of the duct.

No, the gauge install is on MY car (my 95). I can post pics today if you like. Quite simply, it'* right below the stereo.

My boss hasn't done it yet, but will probably put it in either the ashtray door or the upper round vent on the driver'* door. (Riviera).

Ok, note there are some differences to the 95 Riviera in vacuum routing and locations due to engine bay size restraints......but this should be good for all L67 SE/SLE cars from Series 1 years:

Tee fitting installed. Stock tubing is 4mm, my gauge uses .125". 4mmx4mmx.125:

The white faced gauge isn't ideal for the 'look' and feel in the day, but with a red gel-cap on the lamp for backlighting, it'* a perfect match to the dash lights at night. The white does catch the eye better in that particular location, since it'* a little out of the line of natural sight when driving. Ideally it would be better in a pillar pod, which may happen later, but I prefer the sleeper look, and a pillar pod really stands out when you blow by someone. I'll shoot night pics tonight to show the color match. The lamp for backlighting is tied directly into my dimmer control.

To prevent confusion, this is a seperate reply. The follwing three pics are of a 95 SC Buick Riviera, the Boss'* car. (pulley is the OEM pulley from Greenzilla ):




The black box in question. This is NOT a MAP sensor. This is the Evap Emissions Purge solonoid on the Riviera. This solonoid is on the charcoal canister below the airbox of the Bonneville, but the Riv is different as they have no room for the canister in that location:


Another 2 views from farther back:

In the above pic (remember, this is Riviera.....so I'm not sure without looking at the car again), do you see the vacuum line that comes off the FRONT tree above the #5 fuel injector? The middle line directly above the line that goes to the BCS is the line I tapped on my SLE in the post above of my install, and should be appropriate for the Riviera install. This line SHOULD go to the FPR. The vacuum manifold ports on the rear of the SC closer to the TB, to the right of the PCV valve is NOT appropriate for a boost gauge, as this manifold never sees boost, only manifold vacuum.

Thanks A appreciate the very detailed pics. It should be a snap to install. I will probubly mount my gauge in a similar location as I like the sleeper look as well.

Dive......look at installing yours in one of the two door vents for the AC. It looks like a good location on the Boss'* Riviera.
