Ram Diesel Fuel System Recalls: Fuel Leaks and Pump Failures
Ram diesel fuel system recalls here center on fuel leakage and high pressure fuel pump failure. Certain 2019 Ram 2500 and 3500 trucks and 3500, 4500, and 5500 cab chassis vehicles have fuel lines that may leak into the engine compartment. The 2021 pump notice covers certain 2019-2020 heavy-duty pickups and cab chassis vehicles with Cummins 6.7L Turbo Diesel engines, describing sudden stalling without warning. A separate 2022 notice covers certain 2014-2019 Ram 1500 vehicles with 3.0L diesel engines, where pump failure may introduce debris and cause fuel starvation. The 2019 heavy-duty models recur across the fuel-line and Cummins pump notices.
Warning signs to watch for
- 2019 fuel-line recall V76: fuel may leak into the engine compartment.
- 2021 Cummins 6.7L fuel pump recall: the engine may stall suddenly without warning.
- 2022 3.0L diesel fuel pump recall: fuel starvation may cause unexpected loss of drive power.
Can you keep driving? What the notices say
None of these three notices carries a stop-driving or park-outside instruction. Fuel-line recall V76 does not tell owners to stop driving, despite its stated fire risk from leaking fuel near an ignition source. The 2021 Cummins 6.7L high pressure fuel pump notice and the 2022 3.0L diesel high pressure fuel pump notice likewise do not tell owners to stop driving. Their descriptions of stalling and unexpected loss of drive power do not provide a determination about an individual truck's condition.
What the free repair involves
For V76, dealers inspect fuel lines and replace them if necessary, free of charge. The 2021 Cummins pump remedy includes free pump replacement, PCM software updating, and additional fuel system inspection and replacement as necessary. The 2022 3.0L diesel remedy provides free pump replacement and inspection and replacement of additional fuel system components if necessary.

Common questions
Which Ram diesel engines are covered by the pump notices?
The 2021 notice covers certain 2019-2020 Ram heavy-duty pickups and cab chassis vehicles with Cummins 6.7L Turbo Diesel engines. The 2022 notice covers certain 2014-2019 Ram 1500 vehicles equipped with 3.0L diesel engines. Their stated failure mechanisms differ.
Does the Cummins fuel pump recall describe a warning before stalling?
The 2021 notice explicitly describes a sudden engine stall without warning if the high pressure fuel pump fails. Its remedy includes replacing that pump, updating PCM software, and inspecting and replacing additional fuel system components as necessary, free of charge.
Will a fuel-line recall repair also replace my diesel fuel pump?
V76 specifies inspecting fuel lines and replacing them if necessary, free of charge. Pump replacement belongs to the separate 2021 Cummins and 2022 3.0L diesel notices. V76's remedy text does not specify replacing a high pressure fuel pump.
