Help settle an arguement, oil pump shaft

As said above; just go to hardware store, get a 3/8" rod, weld a 5/16" allen/hex on it, and a priming rod is born.

3/8 allthread, hit the end 6 times with a grinder to make a hex...done. Remember to plug or install an oil pressure sender before you spin it or you'll get a guyser of oil up your nose. Ask me how I know this 8-)
