The fuel pump rods have been known to wear off a bit over time, some were a little soft from the factory. I don't remember the correct length, but it was posted on this site at one point, a few years back.

Not to be offensive but I have never heard of the factory FP pushrods being to soft only aftermarket ones
Mopar Performance (purchased from Chrysler dealer) were crap in the 90’s.
