EMAX 3-HP Single-Stage Cast Iron Piston Series Pump (13 CFM Displacement @ 0 PSI)

1. I'm a bit put-off by the "polar air" box it arrived in. . . 3rd party shipper?
2. This is a bare unit, no check valve
3. The vent is being replaced, it's a cheap plastic thing with a glass marble inside-I think not.
4. The oil fill cap is the same junk.
5. What type belt? a 4l or 5l? The pulley is somewhere in between.

I have yet to operate the unit. I need to modify said items, find check valve, find rarus Mobil 427 oil "only"which no one sells, so I ordered 2 qts. online- live and learn.

Instructions say...mount on angle iron for ventilation; anyone want to hazard a guess what that means? Right now I can think of a better use for a length of angle iron, except the compressor won't hold rarus 427 after I'm done- grrrrrr.
