Difference in fuel pumps?
OP: Did the eccentric look deep, like this one?
Mopar Performance Moly-Coated Fuel Pump Eccentric
The arm should stick straight back out of the pump about 4.5". Attached is a pix of a known working SBM pump for reference.

You ought to be able to look right into the timing cover and see if the eccentic stick out well past the centerline of the space between the 2 mounting holes.
I'd buy a Carter direct from Mancini next time. At least there is a step of knowledge in the parts at work. I give NAPA a higher rating than AZ for selling the right parts.
It's been suggested that the OP turn the eccentric to 7 o'clock and see if there is pressure on the arm when trying get the bolts to line up. If no pressure is on the arm when installing like this, then it is not engaged. We don't know this answer.
