Detailed Product Description

The Delphi FP10501 fuel injection pressure regulator is engineered to maintain a steady fuel pressure of 44 psi within the fuel injection system. Its metal body provides durability and resistance to wear, suitable for the demands of Nissan Pulsar NX and Sentra engines. The regulator features a push-in inlet port measuring 0.43 inches (11.0 mm) and a hose outlet port of 0.31 inches (8.0 mm), facilitating proper fuel flow and compatibility with OEM fuel lines. With one inlet and one outlet port, the design simplifies installation and reduces potential leak points. The bolt mounting type ensures a secure fitment in the engine bay, maintaining system integrity under various operating conditions. This part is non-adjustable, matching factory specifications to deliver consistent fuel pressure without the need for manual tuning.

Applications and Problem Resolution

• Maintains consistent fuel pressure for smooth engine operation
• Prevents fuel pressure fluctuations that can cause poor engine performance
• Addresses issues related to fuel injector malfunction due to incorrect pressure
• Helps reduce engine hesitation and stalling caused by fuel delivery problems
• Supports efficient fuel combustion and emissions control

Installation Notes and Tips

• Ensure compatibility with Nissan Pulsar NX and Sentra models before installation
• Inspect fuel lines and connectors for wear or damage prior to installation
• Use appropriate tools to secure the bolt mounting firmly without over-tightening
• Verify that inlet and outlet ports match existing fuel line diameters (0.43 inch inlet, 0.31 inch outlet)
• Check for fuel leaks after installation and before engine startup
