PMD Products 5/16-Inch Hex Engine Oil Pump Primer for use with Ford 351, 400, 429, 460 engines

I used it on my Ford 460 engine. It worked well. The flat spots on the shaft where the drill chuck clamped insured no slippage.

Worked perfectly for my Ford 460.

Couldn’t be easier to use. Had to run my drill in reverse because it is a marine right hand rotation but it got the job done. Make sure you use a powerful drill and you’ll be happy.

Work as it was designed to do.

Simple easy to use.

well made. perfect.

great tool

delivered as advertised. i am a happy camper
