Common Replacement Reasons

  • Fuel pressure that is too high or too low at the rail
  • Hard starting caused by unstable fuel delivery
  • Rough idle or hesitation under load
  • Fuel odor or pressure loss related to regulator wear
  • Check engine concerns tied to fuel system pressure control

Installation Notes

Use the included O-ring during installation and verify the reference port connection before starting the engine. Because this regulator is a direct-mount, return-style unit, confirm the fuel system layout and operating pressure requirement match the vehicle before replacement. For Audi and Volkswagen applications, compare the existing regulator and OE reference number to the vehicle listing, especially on models such as Audi A4, A6, S4, and Volkswagen Passat or Corrado.

Quality Assurance

Standard Ignition supplies this PR401 regulator as a new replacement component with cast iron and steel construction for fuel system service. The included caution sheet provides handling guidance during installation and setup.
