Where do you get the "t" fitting from?

 

 

I got mine from AutoZone, they have a bunch in the "Help" section, with the manual window arm thingies, im sure you know what I mean. There should be one, I think its a 3/16 or 1/8, that the rubber will slip right on, and the Nylon hose will slide in snugly. I used some sealant though too. Hope this helps.

 

Good Man, thanks Tony. It looked like my box was opened when I got it so I wanted to make sure the t-fitting didn't come with the gauge. I'm gonna install it tonight.

 

just get a normal vac. tee, and run a piece of vac line over the nylon stuff.

 

I just installed a tee and ran the silcon hose over the nylon and zip tied in two places, works great.

 

I wouldnt do that if I was you. In fact I had it done, and when I decided to run silicone vac line all the way instead of the nylon I got 2psi extra vaccum at idle, and 2psi extra boost. That nylon stuff is ****, scrap it as soon as you get it and run real line.

 

Ok, I installed it last night. With the red rubber over the light, it matches perfectly with the interior lights. How do I check for leaks? Vac hangs out at around 20. The most boost I saw was almost 5 psi. Does that sound right? I have an HKS filter and Single exhaust with both stock cats and FCD. I'm thinking that I probably should boost at least a full 5 psi or maybe a little more. I'll probably change the line like rx7_turbo2 says.

 

I have RB 3in TB exhaust, and mine does the same. I dont know if: theyres something wrong with my turbo, this guage is a POS, or it has something to do with the vacuum line. I dont understand how you could run anything besides the nylon into that little hole in the back of the guage. Know what I mean. I think I should be boosting to atleast 8 or 9 psi, but I think the highest ive seen is like 6.5 Ive got a K&N intake, im just TOO lazy to put it on. I also ran out of nylon, so I had to run silicone hose from the end of the nylon to the tee.

Real line being....?

 

By "Real Line" I mean real vacuum line, silicone or rubber it doesnt matter. The nylon tube goes in a hole on a nut that screws to the gauge. Take all of that off and put the vac line right onto the threaded part of the gauge. You will notice a big difference.

 

How do I keep it on the guage?

 

Zip ties.

I tried to verify the accuracy of my gauge this weekend and found I have a leak in my line somewhere, probaly where I put the vac line over the threaded part on the gauge. The real way to do it is to find a nut with a barbed nipple, that can screw onto the gauge, and use some teflon tape to seal the whole thing up
