Standard PR221 fuel injection pressure regulator for the 1993-1997 Infiniti J30 V6 3.0L and other vehicles keeps the fuel pressure in the injection system at its set level.
A failing regulator can show up as hard starting, a rough idle or a fuel smell. A weak fuel pump, a clogged fuel filter or a faulty injector can be behind the same signs, so find the cause before you buy. If the regulator is at fault, this one replaces it.
This regulator fits the 1993-1997 Infiniti J30 V6 3.0L and the 1990-1996 Nissan 300ZX V6 3.0L, and the quantity for each is one.
