Recommended Supporting Parts
Protect your high-pressure system and maximize longevity with these proven combos:
- Lift Pumps (AirDog / FASS) – improves filtration and supply pressure to the CP3.
- Exergy Injectors – choose Exergy-brand injectors for your platform (filter by LLY/LBZ/LMM or Cummins 6.7L).
- Gaskets & Seals – refresh sealing washers and rail sealing hardware during service.
- Shop All Exergy Performance – injectors, pumps, and fuel system components.
Install Notes
- Relieve fuel system pressure before removal; cleanliness is critical for rail components.
- Torque to manufacturer spec; verify for leaks after priming and first start.
- No tuning required; custom calibrations may optimize results on higher-flow builds.
Frequently Asked Questions
Q: Why upgrade/refresh the PRV?
A: A worn or weak PRV can vent rail pressure prematurely, causing low-rail codes, limp mode, or inconsistent fueling under load.
Q: Will this cause hard starting or idle issues?
A: When installed on a healthy system, no. The Exergy-calibrated valve is designed to maintain OE-like behavior at idle and cruise.
Q: Do I need a lift pump?
A: Highly recommended. A quality lift pump improves filtration and CP3 feed pressure for overall system health. See our lift pump options.
Q: Which injectors pair best?
A: Stay within the Exergy family for matched flow and quality control. Browse Exergy-brand injectors and filter to your engine (LLY/LBZ/LMM or Cummins 6.7L).
Q: Warranty?
A: Covered under Exergy’s manufacturer warranty. Keep proof of purchase and follow proper installation/filtration practices.
