Product Details

The Bosch 993-110-199-81 is an OEM-specification fuel pressure regulator operating at 3.8 bar (55 PSI). Supplied by Bosch as original equipment, this regulator maintains consistent fuel rail pressure within the fuel injection system to ensure precise fuel delivery, smooth idle, and optimal engine performance.

This regulator is a direct-fit, drop-in replacement for the original unit. It supersedes and replaces the earlier part number 993-110-199-00. Also commonly referenced as the Fuel Injection Pressure Regulator or simply Pressure Regulator.

Key Features:

  • OEM Bosch fuel pressure regulator — factory-specified quality and materials
  • Operating pressure: 3.8 bar (approximately 55 PSI)
  • Maintains stable fuel rail pressure under varying engine loads
  • Direct OEM replacement — no modifications required
  • Includes O-rings necessary for proper installation
  • Replaces OEM part number: 993-110-199-00

This Bosch fuel pressure regulator is the correct OEM replacement part for applicable Porsche vehicles. Installing a fresh regulator restores proper fuel system pressure and helps eliminate symptoms such as rough idle, hard starting, poor fuel economy, or rich/lean running conditions caused by a failing regulator.
