I kinda figure this group may have the answer to a question popped up cleaning Dad's shop. Found old sealed metal-top cardboard can showing part number "GM" "5184531" "Fuel Pump". Is there any way to backtrace this number to find which of his old project cars it would fit? Can's about 4-in tall, 5-in diameter. Picture on can sure doesn't look like any fuel pump I've seen--has what I think is a ring of protruding hex-socket bolt heads in what looks like a flange. Teach me, folks. By the way, Chevy house just laughed and wanted to open it up. Moral: label spare parts.
