Bosch 2007.5–2018 Ram 6.7L Cummins Fuel Rail Pressure Relief Valve 4938005 (1110010013)
Description
The Bosch Fuel Rail Pressure Relief Valve is a high-quality replacement for the factory pressure relief valve used in 2007.5–2018 Ram 6.7L Cummins high-pressure common-rail fuel systems.
The pressure relief valve plays an important role in protecting the high-pressure fuel system by allowing excessive rail pressure to be relieved when necessary.
If the factory valve is leaking, weak, or no longer sealing properly, it can contribute to difficulty maintaining commanded rail pressure and negatively affect engine performance.
This genuine Bosch replacement provides a proper repair without resorting to permanently blocking the factory pressure-relief function.
Features
- Designed for 2007.5–2018 Ram 6.7L Cummins
- Genuine Bosch fuel-system component
- Cummins Part Number: 4938005
- Glacier Diesel Power SKU: 1110010013
- Direct replacement for the factory fuel rail pressure relief valve
- Restores proper pressure-relief functionality
- Maintains an important high-pressure fuel-system safety function
- Excellent replacement for a leaking or damaged factory valve
- Quality alternative to permanently plugging the fuel rail
Why the Pressure Relief Valve Matters
The 6.7L Cummins Common Rail system operates at extremely high fuel pressure.
The fuel rail pressure relief valve is designed to remain sealed during normal operation while providing a controlled method of relieving excessive pressure when necessary.
Over time, a worn or damaged valve may begin leaking fuel back through the return side when it shouldn't. This can make it more difficult for the fuel system to build or maintain the commanded rail pressure.
Rather than eliminating the pressure-relief function with a solid plug, replacing a faulty valve allows the system to retain the protection built into the original design.
When Should It Be Replaced?
A fuel rail pressure relief valve should be properly diagnosed before replacement.
Potential symptoms of a leaking or damaged valve may include:
- Difficulty maintaining commanded rail pressure
- Low actual rail pressure
- Hard starting or extended cranking
- Performance issues under load
- Excessive fuel returning through the relief circuit
- Rail-pressure-related diagnostic trouble codes
These symptoms can also be caused by other fuel-system problems, so proper diagnosis is recommended before replacing components.
Applications
Designed for:
- 2007.5–2009 Dodge Ram 2500 & 3500 6.7L Cummins
- 2010–2012 Ram 2500 & 3500 6.7L Cummins
- 2013–2018 Ram 2500 & 3500 6.7L Cummins
Important Notes
- Cummins Part Number: 4938005
- Glacier Diesel Power SKU: 1110010013
- Bosch fuel rail pressure relief valve
- Designed for applicable 2007.5–2018 6.7L Cummins applications
- Properly diagnose low rail-pressure concerns before replacing components
- Maintain extreme cleanliness when servicing Common Rail fuel-system components
- Verify vehicle application and part number before ordering
Glacier Tech Tip
If you're experiencing low rail pressure, don't automatically assume the relief valve is the problem.
A Common Rail system has multiple components that can cause actual rail pressure to fall below commanded pressure. Proper diagnosis can save you from throwing expensive parts at the truck.
If testing confirms excessive fuel is passing through the relief valve when it should be sealed, replacing the valve restores the factory-style pressure-relief function without permanently plugging the rail.
