I have that pump also, how do you handle the oil mist from the exhaust side of the pump?

I'll ask you what I asked Chuck123Wapiti, how do you handle the oil mist from the exhaust side of the pump?

its mineral oil I don't do anything with it. But I don't stand over it huffing it either lol. My machine is out in the garage so well ventilated and about 6 foot of tubing away from my work.

Worked in a prison for 30 years if I aint shiny every time I comment its no big deal, I just don't wave pompoms.

or 14.6954 if you want a couple more decimal places.

no big deal unless your at 6900 ft like me lol. 11.3 here approx.

My place is 29ft above Irish Sea Level, or about 10 ft above Mean Sea Level of the British Isles. I was told many years ago that mean air pressure here is about 15.1 lb

Al speling misteaks aer all mi own werk..

Here you go for all the atmospheric pressure measurements you'll ever want!

https://en.wikipedia.org/wiki/Atmospheric_pressure

Quoted from Wikipedia:  The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1050 mbar (105 kPa; 31 inHg), with record highs close to 1085 mbar (108.5 kPa; 32.0 inHg). The lowest measurable sea-level pressure is found at the centers of tropical cyclones and tornadoes, with a record low of 870 mbar (87 kPa; 26 inHg).

https://www.engineeringtoolbox.com/air-altitude-pressure-d_462.html for altitude versus atmospheric pressure calculations and table.

For conversions 1 psi = 6.8954 kPa.  So the record high in Siberia of 108.5 kPa = 15.74 psia while the lowest 87 kPa = 12.62 psia

Calgary AB atmospheric pressure runs around 88 kPa (12.77 psia).  This is uncorrected to sea level, so not the same as you will see used by the weather office, but the same as used to calibrate airplane altimeters.  Weather office currently shows 101 kPa here.

I could tell you a story about an engineering firm doing tests for designing an electrostatic precipitator, but we are already way off topic.

Irish Sea Level? If Irish Sea Level is 19 feet lower than the rest of the sea, It seems that there would a pretty good infow from north/south or both ends to level it out. 

It would seem that it should be fairly close to the mean sea level.

So much leather...so little time.

That would work. Mine is in a second floor shop, sending it out through the window would be interesting. I wish I knew what the thread was in the body housing. Any idea?

As Chuck said . . .  nothing to worry about . . . I have about a 6 or 8 ft nylon tubing on mine  . . .  it sits on a shelf . . . never saw any oil residue of any sort on it or around it.

May God bless,
