So my buddy treated my vac pump like how he treats his company tools and now it's NFG!!
I can't get to mad at this guy I did hit a pothole with his ride and split the oil pan wide open. I payed to fix it.
Now he has a silently used YJ 7 CFM Bullet pump. I was thinking of throwing a micron gauge on it and if it pulls down to specs and holds its good. I don't wanna accept junk. My pump worked but was old and ruff. This one is mint and slightly used.
So is that all I can do is use the gauge ? Anything else I should look for?
