River City Diesel 6.0L Powerstroke Thumper I High-Pressure Oil Pump (1735370001)
The 6.0L uses high-pressure engine oil to fire its injectors, and bigger injectors use more oil on every injection event. The River City Diesel (RCD) Thumper I is a higher-displacement HPOP for late 6.0L engines running stock to mid-size injectors, supporting up to 225cc conventional injectors. RCD says its HPOPs offer the highest displacement in the industry.
Key Benefits & Features
- Injector Support: Supports up to 225cc conventional injectors.
- Remanufactured with New Internals: RCD remanufactures its pumps with all-new check valves, heads and shafts for long-lasting performance.
- Part Number: River City Diesel 1735370001.
- What's in the Box: (1) RCD Thumper I high-pressure oil pump.
Fitment
- 2005–2007 Ford F-Series 6.0L Powerstroke Diesel with the late-style cast-iron HPOP
- Will not fit 2003–2004 engines, which use a different HPOP design
Tech & Installation Notes
- STC Fitting and Seals: The snap-to-connect (STC) fitting is a known 6.0L failure point, so replace it and the pump seals while the pump is out. Ask us whether your pump ships with a new STC fitting: if it does, the Alliant AP0099 installation kit covers the seals; if not, the Alliant AP0098 kit adds an updated STC fitting.
