Fuel pump pushrod failure

Has anyone else been struggling with fuel pump pushrod wearing out? My dad has had three fail in two years on two different big blocks.
The car only gets puttered to shows on weekends. Super low miles.
Two of them were from comp he can't remember the third but it was from the parts store.
Do we need to start hoarding OEM fuel pump pushrods?
Is the old man screwing something up?
Been seeing that more often over the last decade or so.
Probably same issue as with the cams and lifters of late.
(sub par metals)

Awhile back I saw hardened pump rods that solved that issue, but don’t remember where, sorry.
That is the solution though.

Went and looked it up.
