A failing oil pressure sending unit leaves you guessing about one of the most critical readings your engine relies on. All Classic Parts' direct-replacement sending unit restores accurate oil pressure signaling to your 1989-1993 Mustang, eliminating false warnings or dead gauges with a part built to OEM specifications.
Replaces a damaged or failing unit. When the oil pressure warning light sender degrades, it can trigger false alarms or, worse, go silent when pressure actually drops. This replacement restores reliable signal output so the warning system works as Ford intended.
OEM-spec fitment on a 1/2-18 thread. The sending unit matches factory dimensions and thread pitch, seating correctly in the block without adapters or modification. Proper fitment also ensures an accurate seal, preventing oil seepage around the port.
Original appearance and functionality. The unit matches the factory look under the hood, keeping the engine bay correct for stock restorations or daily drivers. It cross-references directly to OEM part number E9TZ-9278-A for confident purchasing.
