OIL PRESSURE GAUGE SENDING UNIT (NOT FOR THE DUMMY LIGHT). FITS 1988-1997 XJ6 (SEE #12 IN SECOND ILLUSTRATION) & 1993-1996 XJS 4.0 & 6.0 (SEE #21 IN THIRD ILLUSTRATION). This is the updated smaller unit that will always show pressure unless engine pressure drops. If your gauge drops to zero at stop lights this is the correct replacement.
