I have a freshly prepped 406 block that I got back from the machinist. When I turned it upside down on the stand, a rod fell out and landed on the floor. It is not the solid polished rod for the fuel pump (that is still in place), but rather what looks to be an aluminum tube with a flared end, about 7 inches long. Honestly, it looks like a straight piece of metal fuel line, but it fell out of the block from somewhere. Is this thing just a misplaced fuel line scrap that ended up in the bag at the machinists, or is it something important?
Thanks for the advice,
