Dalton Hathaway Posted November 27, 2019 Share Posted November 27, 2019 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.
