[QUOTE="RBuffordTJ, post: 200659, member: 1385"] You will need a pressure gauge, like a MityVac style pump. You have to be very careful NOT to over pressurize it or you will blow the seals and they will leak for sure. It is not much pressure at all, like 5 psi for 5 minutes to see if you have leakdown, and if not up to about 10 for 10 minutes. Nothing major but you would need the pump with gauge, hose and fitting for the lower unit. Bufford [/QUOTE]
