I recently purchased a 1971 M352A, Deuce and a half cargo truck. When I purchased it the air line from the block under the dash to the air pressure gauge was missing. I plugged the hole and that stopped the air leak. Now I noticed that when the truck runs the Midland air compressor runs continuously and never shuts off. The pressure keeps releasing under the truck midway back. My question is shouldn't the air compressor cycle in and out? And if so does it have a cycling switch? What would make the compressor run non stop? Thanks for your help.
