A failing oil pressure sending unit leaves you flying blind on one of the most critical engine parameters, with either a dead gauge or a warning light that stays on regardless of actual oil pressure. All Classic Parts' direct-replacement sending unit restores accurate oil pressure monitoring to your 1994-1998 Mustang 5.0L and larger engines, matching OEM specification E9SZ-9278-A for a proper, no-fuss swap.
Replaces a damaged or failing unit. When the factory sending unit fails, the oil pressure warning light stops functioning reliably. This replacement restores that signal path so the gauge and warning system respond to actual oil pressure conditions, giving you accurate feedback every time you turn the key.
OEM-spec fitment on a 1/2-18 thread. The sending unit matches original equipment specifications, including the 1/2-18 thread pitch, so it threads directly into the factory port without adapters, modification, or sealant guesswork. Restoring the factory fit also means the connector and wiring harness seat correctly the first time.
Original appearance and function, preserved. Beyond the electrical function, the unit matches the factory profile so the engine bay retains its stock look. For owners maintaining a correct restoration or a daily driver that needs to pass inspection, that visual match matters.
