Hi Bill,
When I bought this hose I was told it was for this application. You might be correct and I will see which one I should have. Thank you very much for bringing this to light! The red corbin clamp was removed from the unit and it was definitely the one that came on this unmolested pump. (Even those hoses are the correct original date coded examples.) I have also seen Wittic screw clamps used for this type of application.

On a separate not Bill..... the negative cable I bought from you a few months ago was NOT the one you see on this engine. I bought the reproduction to see how close it was to my original so I could point out the differences during judging. (Both positive and negative cables are NOS originals.)
