After filling the pump with the supplied oil, the pressure gauge only registers the presence of oil in it. Two things were missing from the picture. Teflon tape and gloves. The company refunded me $6. So the price was the same as the cheaper ones. If you consider that I have to buy more oil, then this kit costs more money. Instructions are funny, written by non-English speakers. Thank you for the phone. Other kits appear to come with instructions. A good thing is a leak detector. But again, the instruction for the detector is ridiculous.
