You need one of Uncle Kent's gauges. https://youtu.be/QSz6GhEMV00

What do you folks that still work on CIS have for a gauge set? I have the HF Pittsburg set that has the fittings and hose assembly to do it. I hooked it up and did not seem to get accurate readings. It almost seemed like the pressure would go into the gauge one way, and not lower when it should. These have schrader valves in the fitting connections on the FD and WUR, as well as the other ends of the CIS hose assembly, and the hose assembly to the gauge and the gauge itself. I have had this set for a long time and figured it was a POS. So, today I went to HF and bought their new version of this that is now called Maddox. It has the same sorts of connections. With this one, I am starting with the system pressure and it shows below spec, but depending on how I move the hose, the pressure rises to where it appears to be in spec. Pushing the gauge in further in the quick connect alters/raises the reading as well. I can't be certain the reading is accurate. This one also seems to be doing the one way thing letting pressure into the gauge and no out. I have to actually remove the gauge from the quick connect and press in its valve manually and it releases. In other words, I just do not trust it. So, anyone have a set they recommend? _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
