Genuine Infiniti FX37 Fuel Pressure Regulator

The Infiniti FX37 Fuel Pressure Regulator helps keep the V6 running with the right pressure at any throttle angle for smooth power and trusted efficiency. The small-sized Fuel Pressure Regulator is seated on the rail and constantly balances the output of the pump with engine demand. The spring diaphragm and vacuum port react in milliseconds, so the pressure drops at idle but rises the instant the pedal goes down. A Fuel Pressure Regulator isn't one unit that fits all. Unlike an off-the-shelf model, each one has been engineered for a different Infiniti build year. As a result, it bolts straight onto early or late FX37 trims without adjustment. Instantly, it restores factory fuel maps. There are two different styles on offer, a pressure-reducing version that remains open until the set point is reached and a back-pressure version that stays closed until the upstream force exceeds spec. Whatever version you choose to use, it will use the same feedback that makes the Fuel Pressure Regulator famous for reliability. As your car's fuel efficiency system works, you may notice faster starts, a cleaner combustion system, and fewer tailpipe emissions. The engine control module sees stable rail readings that allow it to adjust injector timing for more miles per gallon. The benefit feels immediate in an Infiniti FX37. Fuel Pressure Regulators with consistent pressure keep one's high-precision injectors protected from washdown while they also prevent dangerous lean surges. This adds yet another level of safety that makes this product stand out in an already crowded space. As the device utilizes common mounting and vacuum routing across the AWD, RWD, and limited versions, the stocking of one Fuel Pressure Regulator can serve the complete garage of Infiniti crossovers, thus cutting downtime and cost. Road testers rave about the FX37 response after a new Fuel Pressure Regulator, with livelier pull and smoother idle, showing that a small part can deliver a big upgrade. Likewise, runs in an Infiniti FX37 sport and an Infiniti FX37 AWD show the Fuel Pressure Regulator holds pressure in hard corners.
