- 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.
