CP4 Fuel Pump Failure
Most affected vehicles
Ford F-550 Chassis CabCutaway
Ford F-550 Chassis Cab, Cutaway, Crew Cab, Regular Cab (2011-2014, SCAT engine code / 2015-2016, R2GA engine code with CP4 pump)
Failure mileage range
80,000-150,000 miles
Typical failure window
Root cause
The Bosch CP4 high-pressure fuel pump uses a roller-and-cam design lubricated by diesel fuel. Low lubricity UK fuel, air ingress, or water contamination causes the pump to self-destruct, sending metal fragments throughout the entire fuel system - injectors, rails, lines, and tank.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Preventative - CP4 Bypass / Disaster Kit - Install pump protection kit before failure | £1,200 - £2,000 | £800 - £1,500 | Fitting lift pump or CP4 bypass kit / disaster prevention system to catch debris | Prevents failure entirely; recommended for any pre-2017 F-550 |
| Full Replacement - Complete Fuel System - After CP4 failure | £12,000 - £18,000 | £8,000 - £12,000 | Replacement CP4 pump, 8 injectors, fuel rails, lines, tank clean, filter housing | Restores engine but original CP4 pump design remains fitted |
| Full Replacement - Upgraded DCR Pump Conversion - Best long-term solution | £14,000 - £20,000 | £10,000 - £14,000 | S&S DCR pump conversion kit (removes CP4), new injectors, full fuel system replacement | Permanent fix; eliminates CP4 risk entirely; 200,000+ mile life |
Our recommendation
For 2011-2016 F-550s still on the original CP4, fit a preventative kit (£800-£1,500) immediately - this is the cheapest insurance you can buy. If your CP4 has already failed, spend the extra £2,000-£3,000 on the DCR pump conversion rather than replacing like-for-like. The CP4 will fail again on a high-mileage commercial truck. On an F-550 worth £15,000-£25,000, a £10,000 DCR conversion keeps the truck on the road for another decade.

Introduced in 2011 as Ford's first in-house diesel design (codenamed "Scorpion"), it replaced the short-lived 6.4L and has undergone four major revisions - SCAT (2011-2014), R2GA (2015-2019), R2GB (2020-2022), and R2GC (2023+). The 6.7L produces between 300hp and 475hp depending on model year and tune, with torque figures ranging from 660lb-ft to over 1,050lb-ft .
