Frequently Asked Questions
Q: Why choose a 2200 bar PRV versus higher-pressure “race” valves?
A: 2200 bar is a balanced choice for tuned street/tow trucks—high enough to avoid nuisance venting, but conservative enough to protect rails, lines, and injectors.
Q: Do I need tuning after installing this PRV?
A: Not specifically for the PRV. However, if you’ve upgraded injectors or CP3 capacity, proper calibration helps rail control.
Q: Is this a direct-fit part?
A: Yes—installs in the factory PRV location on listed Cummins/Duramax applications.
Q: What if I need a different opening pressure?
A: Exergy offers additional PRV options (race-only variants). See our fuel rail components category or contact CPP Diesel.
