Delphi FP10400 fuel injection pressure regulator for the 1999-2004 Nissan Frontier V6 3.3L and other vehicles controls fuel pressure at the injectors. This Delphi fuel injection pressure regulator comes from a line built in two designs that help meet emissions standards while covering a wide array of domestic vehicles.
- Precisely manufactured internal valves, diaphragms and springs for performance under all engine operating conditions
- Nitrile™ diaphragms that resist high-ethanol fuels and suit a wide range of fuels
- Quiet operation with no audible regulator noise
- Consistent, predictable fuel pressure throughout the system's range of control
Quick facts
- Part: Delphi FP10400 fuel injection pressure regulator
- Fits: 1999-2004 Nissan Frontier V6 3.3L and other vehicles
- Condition: New
Low or erratic fuel pressure, hard starting or rough running can mean the regulator is worn. Before you replace it, rule out a weak fuel pump, a clogged fuel filter or leaking injectors, which share some of these symptoms; a shop can pressure-test the fuel system.
Fits
The listings cover a wide range of Nissan, Infiniti and Mercury models, led by the 1999-2004 Nissan Frontier V6 3.3L, the 1996-2000 Nissan Pathfinder V6 3.3L and the 2000-2004 Nissan Xterra V6 3.3L. Each takes a single regulator.
