    Rated 5 out of 5 by from I was going to modify an old distributor to prime my new engine because I know some of these things won’t prime both sides. I bought this and it works flawlessly.

    Rated 5 out of 5 by from Much improved Oil Pump Primer Some fifty years ago I made my original one from brass bar stock. However at 73yrs my tool box is like my memory "scattered". However, my son-in-law will continue to enjoy this new improved one as I did when installing a new engine in my boat. Excellent tool, maybe large enough not to loose.

    Rated 5 out of 5 by from Jegs Oil Pump Primer Tool This is a good tool for the money. I like the aluminum support bushings to keep the tool tight in the block. That eliminates damage to the oil pump and makes priming the oil system a snap.
