Features:
Anyone who has dealt with fuel starvation issues knows how frustrating it can be when a truck starts pulling air instead of fuel just because the tank level drops too low. The Fleece SureFlo Performance Fuel Sending Unit was designed to eliminate those common problems while providing a cleaner and more professional solution for trucks running aftermarket lift pumps. Instead of cutting into the tank or installing a sump, this system fits directly into the factory sending unit location and works with your existing tank configuration. Additionally, the integrated bucket design helps ensure a consistent fuel supply by keeping fuel available where your lift pump needs it most. This means fewer worries about cavitation, improved reliability, and greater confidence whether you're towing, daily driving, or putting your 12-valve Cummins to work. Factory-style quick disconnect fittings simplify installation and help maintain a clean factory appearance. For owners looking to modernize their fuel system without creating unnecessary complications, the SureFlo delivers a practical upgrade that solves real-world problems.
Designed specifically for 1991-1997 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L 12-valve Cummins, the SureFlo Performance Fuel Sending Unit combines OEM-style fitment with features tailored for aftermarket fuel systems. Fuel is both drawn from and returned to the bucket assembly located at the base of the unit, helping maintain a steady fuel supply even when tank levels are low. Furthermore, integrated one-way check valves allow fuel to enter the bucket efficiently, supporting consistent pump operation and reducing the likelihood of drawing air into the system. The unit features a heavy-duty billet aluminum cap along with universal -8 AN ports, making it an excellent foundation for custom fuel plumbing configurations. New fuel level electronics and an included fuel float help restore accurate fuel level readings while replacing aging factory components. A new tank flange seal and adaptation pigtail connector are also included to streamline installation. Tested with high-flow aftermarket lift pumps from leading manufacturers, the SureFlo is engineered to provide dependable fuel delivery while eliminating the compromises associated with traditional draw straw and sump setups.
Fitment: 1991, 1992, 1993, 1994, 1995, 1996, 1997 Dodge RAM 2500/3500 5.9L 12V Cummins
Notes:

IMPORTANT: Verify your existing MOPAR sending unit part number is listed in the table below. If your part number is not shown, then it is not verified to fit. Many trucks have been retrofitted over time to gasoline model tanks and the SureFlo will not fit into a retrofitted tank configuration.
