Review on Chevy V6/V8 Oil Pump Primer with 3/8 in Drill Chuck - Steel, Black Oxide - Each by John Murphy

I bought this product after reading the comments and also made a mistake. But I knew it was going to happen and I'm still happy. I did this. I thought the bottom aluminum bushing was actually backwards. So I turned it over, but first I had to bevel the other side so it didn't hit the camshaft. I also machined a new pilot diameter on the aluminum top bushing and turned it over because it fit horribly into the manifold bore. I then added a couple of washers under the snap ring to get rid of the extra goo. Now it works great and it was easier than modding an old distro I didn't have anyway. Yes, it definitely helped that I have a lathe.
