I just came from the dealer today. Priced a new ford pump at $154 canadian (approx $120 american). I had a look at the pump, but since it is sealed I couldn't tell what color the impellor was. The parts guy said they are all the same now. How do I know for sure whether this is the one with the white impellor. It wouldn't make sense to keep the old ones around, but I don't want to assume anything. Anyone with part numbers? I am assuming they will be the same in canada and US.
