Im building a marine engine on the base of 1993 4.3 v6 Chevy block. This block has a newer design, changed that year from mechanical to electric fuel pump. I looked for the online postings for these fuel pumps. I am reluctant to buy a used 1993 original pump and the new Mercruiser or Sierra pump for this application is sold only as a kit for $200-$300+. There are plenty aftermarket postings but im not sure which of these pumps are compatible with this engine. Any word of advice? And do I need a serial number of the block? Thx
