I only have one rear sump. I don't even know what they came on. Dave, the guy I got the first 153 from swapped it to me along with the other pump and pickup tube in the photos. He views this site maybe he'll tell us where it came from. My engine was from a Chevy II and it was front sump as are the boat motors I've seen.
