88-96 in theory. I'd go for a 91-95, 96 is the first year for ODBII so the connector may be different. I'd actually just look for one with the same connector. You can also probably just fix yours. Sending units are a wire wound resistor with a contact that rides on it. Usually the contact has come out of contact with the resistor. There should be 3 wires, one for each end of the resistor, and one for the contact. The couple that I've messed with, one on a caravan, and one on a honda had the wiper come out of contact with the resistor part. I just bent it back and all was well. Depedning on the gauge, it will sit at one extreme or the other when the wiper is not in contact with the resistor anymore. Anyway, go with a 91-95, they should have the same connector, if other years have the same connector, it should work too.
