This TPS applies to the earlier EFI/TBI and 454 MAG MPI / 502 Magnum MPI engine families. It is NOT the correct TPS for the 7.4L L29, ECM-555, or 496/8.1L families — those use 853678T / 8M0221731. Verify your exact engine model, serial number, and existing OEM part number before ordering.

Aftermarket cross-reference: Sierra 18-7630. Sierra 18-7630 is an aftermarket replacement reference only — it is not a Mercury OEM number and does not represent a Mercury supersession. Verify fitment against your exact engine application before ordering.
