Detailed Product Description

The Delphi FP10516 fuel injection pressure regulator is a critical component in the fuel injection system, maintaining a steady fuel pressure of 39 psi to optimize engine performance. Its metal construction provides resistance to wear and corrosion, suitable for the demanding conditions under the hood. The regulator features a threaded inlet port measuring 0.47 inches (12.0 mm) in diameter and a hose-type outlet port of 0.31 inches (8.0 mm), facilitating proper fuel flow and connection compatibility. Designed with one inlet and one outlet port, it simplifies installation and fuel routing. The bolt mounting type ensures a secure fit within the fuel system assembly. This non-adjustable regulator is engineered to maintain factory-specified fuel pressure without the need for manual adjustments.

Applications and Problem Resolution

This fuel injection pressure regulator is compatible with Toyota 4Runner, Celica, and Pickup models, making it a suitable replacement part for maintaining fuel system integrity. It addresses several common fuel system issues, including:

• Inconsistent fuel pressure causing engine performance problems
• Fuel leaks due to worn or damaged regulators
• Engine stalling or hesitation related to fuel delivery irregularities
• Reduced fuel efficiency from improper fuel pressure regulation
• Check engine light triggered by fuel system faults

Installation Notes and Tips

Installation of the Delphi FP10516 requires basic mechanical skills and appropriate tools. Ensure the engine is cool and fuel system pressure is relieved before removal. The bolt mounting type allows for straightforward attachment to the fuel system. Verify that the threaded inlet and hose outlet connections are secure and free of leaks after installation. Since this regulator is non-adjustable, no pressure tuning is necessary post-installation. Always consult the vehicle’s service manual for specific torque specifications and safety precautions.
