A few pointers on Andair 375:
*Isopropynal removes witness alignment marks for proper registration of bowls just as well as it will remove markings on some rulers
*On our model 375, the inlet and outlets are 1/4" NPT threads. The female threads are machined in a square block of aluminium and held in place with 4 flat head screws and sealed with an O-ring. The 4 screws pattern allows the block to be best positioned in case you are using other than a straight fitting (ie 45 or 90 degree). Once you proper orient, there is a dimple in the gasculator that wants you to stake (can use a punch) edge of flat head screws into the dimple to lock screw in place.
