I did not see this mentioned in the thread. A less expensive solution...
Airtex 60932 Mechanical Fuel Pump for 1992-93 Mercruiser Marine 454 and 502 8 Cylinder amazon price 45.00. Then use an upgraded bottom section if you want to.

That's the right name Airtex not Aeromotive, sorry for the confusion. Airtex is O.E. supplier to Merc for the pumps
