This aluminum fuel rail inlet nipple is included in the Zetec conversion kit, but can be useful for anyone that wants a metal fuel inlet nipple with a hose barb instead of the plastic fuel rail pressure transducer with quick connect.  Compatible with Zetec Focus, Contour, Escape, and Escort fuel rails that have ~13.3mm inlet boss. The OD of the hose barb is 7.85mm.
