Hi All!
Ethan just tested four MPS on a '74 2.0 we have here and it seems one holds pressure but it runs erratic. We tested the three other MPS and they tested good. I know that even if an MPS tests good, old MPS's the diaphragm's often fail once pressed back into service. Would the Tangerine MPS diaphragm kit help this, or is there something else likely going on? |
