Visual Identification

Verified visual identification characteristics for the 802632T / 25180245 will be added once confirmed. Do not rely on appearance alone to confirm fitment — always verify by OEM part number, engine model and serial range.

What's Included

Package contents will be confirmed once the replacement product is sourced and verified.

How to Verify Fitment

Step 1.Locate your engine data plate and confirm the exact engine model designation — specifically 7.4L MPI (L29) or 7.4L MPI MIE (L29). The L29 designation is important: not all 7.4L MPI engines use this injector.
Step 2.Record your engine serial number and confirm it falls within the verified serial ranges: 0L010003–0M024330 (7.4L MPI L29) or 0L010003–0L674613 (7.4L MPI MIE L29).
Step 3.Compare your existing OEM part number to 802632T or any of the verified cross-references: 25180245, 17124187, 17121068, 17095004, 8M0051200, or Crusader 49051.
Step 4.If you are uncertain about fitment, contact us before ordering. We would rather help you confirm the correct part than process a return.
