Standard Ignition PR246 fuel injection pressure regulator for the 1998-2004 Nissan Frontier 4-cylinder 2.4L and other vehicles keeps fuel pressure steady at the injectors. As a return-type regulator, it sends excess fuel back toward the tank to hold that pressure.
A worn regulator can show up as hard starting, a rough idle or a fuel smell. A clogged fuel filter, a weak fuel pump or a leaking injector can be behind those signs too, so find the cause before you buy. These engines take one regulator, and this listing is one.
It is listed for a wide range of Nissan models, including the 1998-2004 Nissan Frontier 4-cylinder 2.4L, the 2010-2015 Nissan NP300 4-cylinder 2.4L and the 2000-2004 Nissan Urvan 4-cylinder 2.4L.
