Any idea why these pumps are hard to prime. They seem to get air on them. I have to unhook the lower fitting run them for a bit to get them going. I thought if they were mounted like this they would work better.

According to the March Pump Manual, you do not want any elbows or restrictions within 8" of the inlet. [...]
The actual wording from the March pump General Installation Instructions is:
"Install the pump as near to the suction source and as low as possible. Suction must be flooded. When using an elbow, valve, etc., the suction must have straight piping in length at least five (5) times the diameter of the pipe."
Left unclear is whether the diameter of the pipe is the inside or outside diameter, but I'd think in the context of the discussion it would be the inside diameter, which would make the minimum straight length pipe into the Intake side of the pump head closer to 3 inches than 8...
Cheers!

When you are ready to start the pump, open the priming valve to bleed any air out of the pump, then once you have good flow, close the priming valve and everything should start moving where you want it to. I catch the output in a small bucket so I can add it back into the batch.
Please excuse the foil heat shielding.
