Title
Repairing Mityvac MV8000 O-ring Seals
Introduction
When testing air-tight systems like vacuum lines on an vehicle, you need an air-tight pump. Not to mention, a leaking pump makes pumping automotive fluids much more difficult.
With time, the o-ring seals in your pump will flatten, stiffen, and lose their lubrication. This may cause them to leak allowing air back in to the pump.
The leaking vacuum can lead to confusion when trying to diagnose vacuum systems.
Learn to take apart your hand pump and replace the o-rings.
