I picked up an old Kellogg American 331 tva pump and had a few questions on installing it on my 80 gallon tank. I am trying to find out where to run the line that comes off the center of the cranshaft end cover. Does this line go to tank pressure or does it go to the plug on the side of the head. This cover also has a line that goes up to the head(1/4" copper). There is a pipe plug on the side of the head near the pressure outlet, but it is plugged. I got the unit out of the body shop I worked for. It was in great shape and worked good. But its been awhile since I removed it and cant remember where the line went. Also what would be a good oil to use in this compressor, would any 30weight non detergent work or is there a specific oil that should be used? I may also need some help on the wiring of the magnetic starter and pressure switch but I want to get the pump all squared away first. Thanks in advance. I can get more pics if needed.
