Detailed Description

The Standard Ignition PR158 fuel injection pressure regulator is engineered to maintain the correct fuel pressure at the rail so the engine receives a steady supply under changing operating conditions. Built for select Chrysler, Dodge, and Plymouth models, including 1990 Chrysler Daytona, 1988-1990 Dodge Caravan, and 1988-1989 Plymouth Voyager, this regulator is designed around the original application requirements for fit and function. The PR158 part number is also referenced in interchange listings for related OE-style replacements, and PR158 cross-references Gates 21065 for the same application.

What It Helps Address

  • Fuel pressure that is too high or too low
  • Hard starting caused by unstable fuel delivery
  • Rough idle from inconsistent rail pressure
  • Fuel leakage at the regulator assembly
  • Poor engine response related to fuel pressure control

Installation Notes and Tips

Verify fuel system pressure and confirm the regulator matches the vehicle’s original application before installation. The angled nipple orientation should be matched to the factory hose routing, and the included caution sheet should be reviewed before service. This part is listed for N/A position applications and is used on gas fuel systems only.
