MODIFIED VACUUM TESTER
We all use vacuum to test valve to seat seal. I use a handheld Mityvac in conjunction with an electric vacuum pump. By taking the vent cap off top of Mityvac, I was able to hook the pump directly to it. Now I have the ability to apply, hold and release vacuum with one hand and the gauge is right there on it as well.
