Do not use the nylon tubing. It will leak and have good chance to get kinked.

Go and buy regular rubber hose with 3 or 4mm inner diameter and use that instead. You can get it in any autoparts store together with the T and the straight extension with different diameters on opposite sides that you will need to hook the tubing to the gauge. The gauge will have better response and be more accurate.

You will also need short (2") piece of rubber tubing with 10mm inner diameter. You then take that tubing and slip it over the threaded end of the gauge. Then you insert straight extension that has two different diameters (one to fit the 10mm hose and one to fit the 4mm hose) into the 10mm tube. Then just connect the 4mm tubing to the other end of the straight extension.

The T is attached to the hose that runs between the intake manifold and the FPR on the back of the engine. Just cut the hose in the middle and remove approx 1/2" from the hose. Then insert the T. Here is nice picture of T junction. :)



To get the hose from the gauge to the engine bay just thread it through the ECU box and then through the rubber grommet through the second firewall. I used coat hanger that I threaded from the ECU box to the inside of the cabin. Remove the fuse box cover and when you insert the coat hanger you will see it come through. YOU NEED TO DISCONNECT THE BATTERY because there is a chance of the coathanger touching the relays and live wires going to the fuse box.
Then just attach the hose to the coathanger and pull back out. Once the hose is in the engine bay, cut to proper size and attach to the T. You are done.

To secure the tubing use either zip ties, or better yet 8-10mm hose clamps that you can buy at the dealership. They cost around 1.50 each, but they are worth.

I originally used the nylon tubing and it sucked (literally). After about one year I got fed up and replaced it with the rubber tubing. No leaks, and the response is instantenious instead like molasses with the nylon tubing. The whole job takes about 1 hour. Good luck.

Yes, that works, but you have to use the two different diameter tubes and use straight extension with two different diameters (that you can buy in autoparts store).

I'm using the Nylon tubing (I think) from New South Performance from the Turbo Pod. The outside and inside diameter of the line does look small and it's very rigid compared to a rubber hose. I can see where it would be a problem if you accidently kink the line. . . .but I don't have any complaints. I works very well for me and the response seems to be good.

no leaks for me. I'm getting 10-11 psi peak.
