Default new compressor

well my old compressor took a dump and started oiling so i ordered a new pump. replaced all my lines and flushed out the tank. finally got the new pump installed and it went to oiling right off. new one will be here monday.
but i thought i would share a little trick i learned from my compressor guy back in the 70's . if your painting this is important. when you buy a new compressor or replace a pump always loosen the supply line from the pump to the tank. if the pump is oiling it will seep at the fitting and save your air lines. this is common today as most all pumps are made in india . had i ruined 140 ft of new lines i would have been really pissed off
ingersol rand sent a new one out no questions asked. good folks .

glad i caught it before i started a new project .

and I am GLAD you caught it.

Nowadays....I assume NOTHING.

Hopefully this country will start making things again so we know they are RIGHT.

to clear things up a little. the compressors have assembly lube in them . there may be a small amount of oil coming out during the first day running but not much. i ran it for a few min then cleaned the line. did that several times and it cleared up. a little oil is one thing but if it's dripping you have a lot of oil vapor. i plan to put an oil filter between the pump and tank.

I can see how this is an important point which I didn't know after I bought my new compressor last year BUT the manufacturer (Quincy) recommended that I run the compressor at no load for a half hour before using it to paint. So I opened the release valve for this break-in run. While I guess oil residue could adhere to the inside of the tank, did I accomplish the same thing? I did paint and clear my '67 without incident. Thanks
