Appreciate all the replies below. Today we focused on two things. First I worked the pressure control valve loose and then turned it clockwise one full turn. We started with 3 OSI on the gauge and with one full turn down it jumped to 5 OSI. Needless to say this made us pretty happy so I turned it clockwise another full turn and pressure fell off again to 3 OSI. No joy. Anyone familiar enough with these pumps to tell me what this might mean? Bad pressure control valve or bad pump?
While it was up and running I tarped the seed drum holes to get rid of the draft from them and took some fine grass and held it around every seam...drum seal, riveted tank joint, tank lid seal, fan shroud...and I found no more leaks.
Lastly, we raised the planter and filled the drum with seed. Powered up our pump and manually turned the seed drum. Drum held seed in all holes. When the holes came around to the rubber rollers the seed dropped off the drum and fired out past the sensors and onto the ground. It was coming out all 8 tubes. I collected the seed after the test and had 320 seeds which divided by 8 rows came out to 40. Important to me was it was evenly divided by 8. So the tubes are not clogged and operation is completely normal. We just don't read full pressure on the gauge.
Wondering what you more experienced guys think of the above?
