I've been using these for a couple of years, but I just bought a fancy combination tester so I don't need them anymore. Both are older tools that I got secondhand. The Mityvac pump is a basic pressure tester with a gauge, plastic-bodied and non-rebuildable but works perfectly. The pressure tester is just a squeeze bulb pump like you might find on a portable fuel tank for a 2-stroke boat motor, with a gauge and hose nipple. It would be nice to add a hose clamp around the intake end of the pump, because otherwise the bulb sometimes distorts enough when squeezed that the check valve falls loose inside the bulb, and getting it back into place is kind of a pain. $20+shipping.
