I purchased this pump for a DIY AC compressor replacement project. The vacuum pump and manifold gauge set did the job well and have served me on two additional repair projects since then! Noise level is good, easy to use, light weight, and accurate readings.

I don't know, can't remember, but if it has something to do with my truck.It works great ninety four g m c

I recieved this A/C maintenance kit many months before I used it. Over all I think the price was right for what it included. Gauges are OK. Not pro level by any standards but function ok. They definitely need calibrated against a known gage. The hoses are too short. They are about 3 1/2 foot long. 6 foot would have been perfect Ac coolant line couplers are hard to attach. I had to really apply effort to get them to attach. But I the end they fit. The different adapters included are super cool. They support different types of refrigerant cans. I wish the kit included R1234yf couplings. It has ony R134a couplers. I had to purchase a set of R1234yf couplers to connect to my newer trucks. I cant imagine that would have cost much. But I still had to spend 22 bucks. The vacuum pump has its good and bad. It appears to be designed well. The fit and feel is really good. First problem was the amount of oil included was not enough. It only filled the pump 1/4 by the sight window. Im sure it was enough to safely run it. Its quiet and appears built well. But when its running it gets super hot. It does spew out a substantial amount of oil through the top vent. Just in one use (40 min) it spewed out half of the oil I put in it. So that ment that with the provided oil I got just one use. I have to buy more. The storage case is nothing fancy but works fine for occasionall use. The included storage bag is nice to have. It fits the intire kit. Its not something that will hold up traveling around with. Its just a soft sided bag with a handle. It does have fiber material between the inside and outside. Should protect against damage. The gloves are OK but appreciated. The operational manual is quite good. Photos and step by step are good. Way better than other Chinese products. It clearly shows the open and closed direction the couplers need. Many people think closing is clockwise. It important to turn counter clockwise to close and thats needed to make the connection. The gauge valves operate normally. Clockwise to close. Value was added with the leak detector. Its definitely not A grade. It works OK for big leaks. And areas that are accessible. The included storage bag is very nice. Over all if I had used this kit within my return window I dont think I would have returned it. Everything with the exception of the pump gets a 7.5. For the money. Parts are manufactured good. Pump gets a 6. Only because how much oil gets spewed and the chinssy amout of oil it came with. Time will tell if the heat will be a problem. I wish the pump portion had heat fins. The motor never got hot.
