This style pump head is meant to direct-mount onto a certain tapered

going to find on regular electric motors. The pump impeller has the
female of the tapered shaft with the lockbolt, and the tolerances when
it's all bolted together is critical.

The OP listing clearly states "3/4 inch straight shaft with keyway"

O Rly?

I read the eBay listing referenced as a tapered shaft with an end
hole for a lock bolt. Sure you looked at the right page? They :do:
come both ways.

Stolen off the EBay page, Are you confusing tapped with tapered? Bifocals
not working for you?
I have never seen a 3-8 HP gas powered pump with a tapered shaft, and I have
worked on many of them over the years. Straight shaft, threaded, or keyed is
the norm. Generator engines of that size are typically tapered. Keep in mind
on most pumps you need to be able to shim the impeller to keep tight
clearances so the pump will work efficiently.
