Welcome to the Bbs Jim,
Here's a way to test your MPS... quite simple too: Courtesy of Geoff (Bleyseng) Take a standard vacuum auto pump and attach the hose to the MPS. Pump the vacuum up to 15hg on the gauge and if the MPS holds the 15hg for say 5 min or so without much leakdown (2-4lbs) then the diaphram is good. The diaphram could be good but other reasons the MPS leaks are: 1. The case halfs o ring is bad 2. The paper gasket that the diaphram seats to is bad. 3. Someone has adjusted the MPS out too far so the mix screws are leaking. (rare) good luck & post some pics of the car (IMG:style_emoticons/default/beerchug.gif) ..........b |
