What is this thing?
Today I completed replacing the rubber vacuum and pressure (boost) fittings that were in poor condition. I de-flowered the ALDA, backed the adjusting screw out 1-1/2 turns (counterclockwise), and put the ALDA back on the IP.
While working in this area I noticed some kind of adjustment screw with a lock nut, on the IP, just aft of the ALDA. See the picture, the arrow points to it. Anyone know what it is? I'm not gonna mess with it, just curious as to what it does.
(In the photo, you may notice a rubber cap on the ALDA's hose connection. That is to protect ALDA wile being handled. Once the photo was taken, I removed the cap and reattached the correct plumbing.)
