Just remove the rod and have a look at it. A good one will have the same length of metal "turned down" a bit on each end (about 1/2" IIRC). Worn ones will have one end a bit shorter. And don't forget that the worn end of the rod will often wear away on the camshaft lobe too, so even a new one would be "short" and you would need another cam.

Over the years, this rod becomes worn and eventually results in poor performance of the mechanical fuel pump. I checked the 1964 Manual and couldn't find a spec for the rod so I'm reduced to identifying a possible problem while lacking the ability to define it. > > Phil Brust > 73 & 82 Imperial > > > > > > > > > > ----------------- http://www.imperialclub.com ----------------- > This message was sent to you by the Imperial Mailing List.
