bought an autometer gauge and am having trouble installing it. It's a mechanical pro-lite gauge, here are my questions...

1. Where do I t-in to this boost line everyone is referring to under the intercooler? There's a skinny line between the #2 and #3 intake runners that taps into a round metal object (I assume something having to do with fuel delivery) but there is hardly enough room to cut this line, install a T and then run the line for the gauge to it. Another skinny line I found was directly to the left of the S/C to intercooler elbow. There's more room here, but I"m not so sure this is the right line and I don't know if I have enough tubing to stretch it that far. And finally I found yet another line that runs right above the S/C outlet on top of the elbow, this is also a tight fit.

Here's the one that's to the left of the elbow...


And here's the one that's right above the S/C outlet, notice how I can't even get my finger under it.....


2. I need a power source within 6-8 inches of where I"m mounting it on the right side of the tach b/c that's how much they provide, where should I tap into? If not 6-8 inches I suppose I'll have to ghetto rig some jumper wires, but still, where is a good place to tap in?

3. It doesn't seem like the fittings used to attach the skinny tubing to the back of the gauge make an air-tight seal, what should I do to make it air-tight?

 

If mine ever show's up, I'm going to install this.

I'll let you know.. I hop sometime net week.

Thanks

Hey,

MY guage finally showed up, and I'm going to do the install today. I'll take some pics, and hopefully be able to help you out

Thanks

ZAMIRZ -

As far as the vacuum tube goes, you should tee off of the line that comes off of the fuel pressure regulator (with the intercooler off, it is just about centered under where the intercooler would be. It's a shiny cylindrical thing with a vacuum / boost line that comes off the bottom of this unit.) I teed into the first line you have pictured, and the gauge only read vacuum - so on the advice of fellow board member "SUMWON" I teed off of the fuel pressure regulator.

To seal up the fittings on your gauge, use teflon tape on the threads. There should also be a small ferrule that slips over the nylon tube befor inserting into the back of the gauge (slip the threaded cap over the tube first, then the ferrule, then screw into the bacl of the gauge). The ferrule gets crushed in the fitting to aid in making a beter seal as well.

Still haven't done the electrical wiring on mine yet...

Hope this helps!

 

Electrical connection:

The negative wire is easy- just attach to any dash mounting screw/bolt you want to.

For the positive, I tapped into the grey/pink wire from wire harness that goes into the tach. (remove the tach and you will see a wire harness coming up from the steering column - it is attached to the tach by a green connector.)

With this setup, the boost gauge lights up only when the instument lighting is on.

Boost line connection: tee it off the fuel pressure regulator. You have to remove the intercooler to get to it. There is a good pic on this thread:

That's exactly the info I've been looking for on the electrical connections. Thanks!

Gah - just reread my previous post, and my spelling is awful. My grade school teachers would be proud....

I'm still confused....I can't tell from the pic which line Ryan's referring to...is it the black on running from left to right?

 

The cylinder shaped part with the green paint mark on the top is the fuel pressure regulator. The large black hose going into it on the left side is the fuel line. The small black hose that plugs into the bottom of the fuel pressure regulator is the vacume/boost line. It has a 90 deg rubber fitting on it where it plugs into the regulator. I cut that line close to the 90 and inserted a tee fitting to tap into that line for the gage hose. Hope this helps.

Thanks Dan. I thought that was it but it's so thin where do you get a tee to fit that???

 

At your local auto parts store they will have a section for vacuum lines and fittings. The rubber tee I used is for 1/8" hard plastic lines. I think they are used for emmission equiptment on new cars.

I guess Murray's doesn't carry that. Even so...it must have been pretty tought to get your fingers between the plenum to do all that
