If it is the same diameter the entire length then it is probably a grooved dowel pin. If different diameter on one end then a tapered dowel pin. Packard doesn't give any specs other than there is one for junior engines and a different one for senior engine pumps.

McMaster-Carr has many types. You might check out McMaster's offeringsmcmaster.com/. and see if theirs looks proper. Once at the site you could start with a search for grooved dowel pin and then find the one closest to what you have. You can also look for the tapered and some other types for comparison. Possibly you can find one locally once you have the parameters.

As I recall someone else had a similar issue with their fuel pump. Did yours have the retaining clip located in a groove at the center of the shaft or is yours the type that has the housing or a plug peened over the shaft end. I believe there was a question if the kit shaft had the groove for a retaining clip or if they had chosen a different retaining method that might not be satisfactory. Some felt it was better to reuse the old shaft to utilize the clip.

EDIT. It appears the pin you are looking at would be the proper type. One thing you might check before ordering is the condition of the hole. If the old pin broke and there was play, possibly the hole has been enlarged to the point an oversized pin might be needed.
