Fuel Injection Pressure Regulator For Nissan Pathfinder 90-20 For Nissan Xterra

Fuel Injection Pressure Regulator for Nissan

This replacement fuel injection pressure regulator maintains stable fuel rail pressure to ensure optimal combustion and engine performance.

Overview

This fuel injection pressure regulator is designed to regulate fuel flow and maintain the precise pressure required by the fuel injectors. A failing fuel injection pressure regulator can cause hard starts, rough idling, and reduced power output under load. This component is engineered to restore proper fuel system operation for drivers and service technicians servicing utility vehicles.

Built For Performance

• Features a precision-engineered internal diaphragm for accurate pressure regulation.
• Designed to original equipment specs for seamless integration on the fuel rail.
• Includes quality seals to prevent fuel leaks and ensure airtight vacuum routing.

Fits These Machines

• for Nissan Pathfinder 1990-2020
• for Nissan Xterra

On-The-Job Use

• Resolving fuel starvation or rich-running conditions during standard diagnostic repairs.
• Restoring stable engine idle and throttle response in daily driven utility vehicles.
• Replacing leaking or ruptured regulator diaphragms that cause long engine crank times.

Specs At A Glance

Good To Know

Q: What are the signs of a ruptured fuel pressure regulator diaphragm? A: A ruptured diaphragm often lets raw fuel leak into the vacuum line, leading to black smoke from the exhaust, spark plug fouling, and hard warm starts. Checking the vacuum line for fuel is a reliable diagnostic test.

Q: Does this regulator come with replacement seals? A: Yes, this regulator includes the necessary O-rings and seals to ensure a secure, leak-free installation on your vehicle's fuel rail assembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
