Service Overview
Common-rail injection runs at up to 30,000+ PSI with micron-level tolerances. The fuel filters are all that stand between dirty fuel and injectors costing thousands per set.
Service involves primary and secondary filters, water-separator drain, system priming per your engine's procedure, and a leak check under load.
Signs You Need This Service

Consequences of Ignoring It
- Injector failure — the most expensive routine risk a diesel owner faces
- High-pressure pump damage (debris from a failing CP4 destroys everything downstream)
- Stalling and no-starts from clogged filtration
Recommended Service Interval
Every 15,000–30,000 miles per your engine — never stretch this one.
