1980 Mack Semi foot valve hose connections

Recommended Posts

Had to replace the foot valve on 1980 Mack semi truck. I must have the hose  connections wrong, as no air builds up after starting truck. Can you supply a diagram or chart that I can use to check if I have all the hoses connected properly. Thanks.

                     Should be a E-6 valve, sure you don't have the ports mixed up? you have supply going to delivery-Supply should be IIRC 11 and delivery 12- on primary and secondary supply 21 and delivery 22. IIRC


One ping only
