Fuel Pressure Regulator for 1987-1990 Jeep Wrangler & More - Standard Ignition PR150

Hold fuel-system pressure steady and keep the injectors fed with the Standard Ignition Fuel Injection Pressure Regulator PR150 (also cataloged as a Fuel Pressure Regulator). This diaphragm-type regulator drops in as a direct-fit replacement for the 1983-1987 Renault Alliance and the 1984 and 1986 Renault Encore [L4-1.4L], plus the 1986-1990 Jeep Cherokee, 1986-1990 Jeep Comanche, 1986-1987 Jeep Wagoneer, and 1987-1990 Jeep Wrangler [L4-2.5L].

• Diaphragm operation: uses a spring-loaded diaphragm to regulate fuel pressure and route excess fuel back to the tank, helping keep the injectors supplied.
• Operating pressure: rated at 14.5 psi.
• Built for these fuel systems: engineered to suit the fuel-system requirements of the listed Jeep and Renault engines.
• Validation testing: the manufacturer's program includes 200+ hours of vibration testing plus 1000+ hours of extreme heat/cold and on-vehicle testing.
• Durable materials: made from corrosion-resistant, high-durability materials, with seals and thermal-resistant construction intended for reliable operation.

A regulator that can't hold the correct pressure may show up as rough idle, hard starting, poor fuel economy, a fuel odor, or rich/lean running; diagnose the cause first, and if a failed regulator is the culprit, this replaces it. Ships with an instruction sheet and a caution sheet. Made in the United States. Manufacturer part number PR150.
