That's not the SL55 fuel pump. It may have the same flow, but not the same fittings. Believe me, we tried installing a vendors fuel pump upgrade that wasn't the SL55 and it was more of a headache then anything. First it didn't come with any fittings and then when I inquire about the fittings I'm told they are extrememly hard to find and must be welded on. Granted before the pump was ordered I was told they were off the shelf parts. Real great fuel system upgrade.
