CIS test gage modification question
 

Can someone help me figure out what I need (crap, that was a loaded question:eek:)? I bought a Matco Fuel Pressure test gage set a couple of months ago. It said it was for the Porsche CIS systems, but it looks like not for the 911 CIS system. I have been too busy with other things to worry about it and so I am either stuck having to sell it, OR maybe I could just adapt it to what I need. I am guessing I just need the right fitting to make this work. Has anyone had to do this before? I am wondering if I could find an old fitting with a section of original fuel line left on it, I could use the extra fuel line to adapt to what I have with another fitting. My car is an 83, and I am guessing that is 1/8 or 3/16" tubing. How far off am I?

Thanks

Shane the Matco tester I had used the same quick disconnects as the cheap ebay CIS testers. The cheap one I used doesn't need any adapters just remove the line between the WUR and the Fuel Dist.( this has worked on all the CIS 911's I have used it on) I guess what I'm trying to say is keep the Matco definatly if it has a three way valve and buy the cheap one for the lines so you don't need to hunt for adapters....any pics of the Matco that you have?

here is the link to my original thread back when I bought it (it has pics)... I have a valve for it but not shown in the pics...

I think I would sell that and buy one of the cheap ones I think there mad by star products believe it or not most Snap=on guys can get them for between 40-50.00 depending on there mark up.

I made mine up originally for use on my old CIS 924 in this pic, but to use on my 911SC, I think I had to swap the fittings and the hose end for end.

Basically your end goal is to end up with fuel distributor...then gage....then shut-off valve....then warm up regulator. Any way you can get the above into the system between the existing line from FD to WUR will work.

One could probably even get by with some creative use of hose clamps in a pinch, but gas in the eyeballs when a hose pops off (or worse) is not fun.:D
