The high pressure fuel pump feeds the common rail that runs your Sprinter injectors. When it wears you get low rail pressure, no start, or sudden shut down. We test rail pressure, rule out injectors and sensors, then replace the HPFP and bleed the system correctly.
What this service includes
- Measure actual versus target rail pressure with Xentry
- Test the pump, regulator, and rail pressure sensor
- Replace the HPFP and any contaminated components
- Bleed and road test to confirm stable pressure
Signs your Sprinter needs it
- Crank but no start or a stall under load
- Low rail pressure or fuel metering codes
- Metal in the fuel system after a pump failure
What does high pressure fuel pump (hpfp) cost?
Ballpark pricing for high pressure fuel pump (hpfp) on a Sprinter runs $1,500 to $4,000. The final number depends on your model, mileage, and the exact cause, which we confirm with Xentry before any work is authorized. Diagnostic time is credited toward the repair. See the full pricing page.
Frequently asked questions
Why is HPFP failure so serious on a diesel?
When some pumps fail they send metal through the fuel system, which can require injector and rail replacement too. We inspect for contamination before quoting so there are no surprises.
Can bad fuel cause HPFP problems?
Yes. Water or dirty diesel accelerates pump wear. Keeping the fuel filter fresh and using clean stations helps protect the pump.
