Upgrade the fueling capability of your 1994-1998 Dodge Ram 5.9L 12-Valve Cummins with the SWAG Performance 191 Delivery Valve Set. Designed specifically for Bosch P7100 ("P-Pump") injection systems, these performance delivery valves increase available fuel volume, improve throttle response, enhance turbo spool-up, and support higher horsepower applications. These valves are a popular stepping-stone upgrade for diesel enthusiasts running larger injectors, upgraded fuel plates, governor spring kits, and aftermarket turbochargers.
Compared to factory 131 or 181 delivery valves, the 191 design allows significantly more fuel flow and can provide up to approximately 20% additional fuel delivery potential, making them an excellent upgrade for street, towing, sled-pull, and competition applications.
The 191 delivery valve is widely regarded as one of the best fuel delivery upgrades for the 12-valve Cummins platform. By increasing the fuel volume available from the P7100 injection pump, these valves help support:
- Higher horsepower builds
- Increased fueling for upgraded injectors
- Faster turbo spool-up
- Improved acceleration
- Stronger mid-range power
- Enhanced towing performance
- Better fuel system support for future modifications
When combined with common P7100 upgrades such as fuel plate modifications, governor spring kits, larger injectors, and upgraded turbochargers, the SWAG Performance 191 Delivery Valve Set helps unlock additional power potential from your 5.9L Cummins.
Installation Notes
Professional installation is recommended. Proper torque specifications and clean installation practices should be followed when servicing P7100 delivery valve holders. New sealing components are included to help ensure a leak-free installation.
