O'Reilly's has AC gauge set rental with $264 deposit. With a vac pump just short of 500! All fully refundable tho. Think will buy a 75 dollar vac pump as need one to test transmission valve body. I'm tempted to go check with some ex-coworkers and see if can borrow a gauge set and vacuum pump. Right now need to see if it holds vacuum. If it does, "continue to assemble" is the old instructions. The low pressure switch was definitely leaking back couple months ago. It's entirely possible the new Advance Chinese part is leaking too. Let me go see if connector is wet?
Nope. It's dry. Need a black light to look for dye.
