Your 2, suspension air compressors each have foam air filters built into the compressor head. Due to age. They've become a sticky/flaky material that can cause your solenoid valves to leak air from the air bags. A Q tip, and a vacuum cleaner seems to work to get the very small filter material out. Use a 5/16th nut driver to remove the 7 small bolts. Lift off head. You will see the filter, or the rectangle hole that it did reside in. Haven't found a replacement filter material YET. But will notify when I find a replacement. At this point. No filter is better then what you have now. This late system is very simple. Compressor, start relay, solenoid valve, and an electronic eye. One set for each side. Bob Dunahugh Late 78 Royale
