How it works.
The rod does not connect to the engine, it just slides up and down.
The top end of the rod rides on the cam shaft.
The cam pushes the rod down and the spring in the pump pushes it up.

Thanks for your post - do I need to grease that rod? My perception was that some people apply grease as a way to help hold the rod up in place...if I'm able to do that without the grease (using the hacksaw blade for example), then do I need to grease it? I presume that rod is lubricated by engine oil while in service?
This job isn't overly complicated, but access is a bit tough due to the exhaust headers I have on it, as well as the lower radiator hose...if that wasn't there, it would be a lot easier. Since nobody has mentioned this hose, I almost wonder if I have an incorrect hose...but that's for another day!

The lower radiator hose is correct, it tight there but it should not be a issue.
Thanks to all of you for your help...now on to the next issue!
