Diesel fuel system on other 2500 years
No other 2500 model year has enough reports of diesel fuel system for a sheet of its own. See every 2500 year.
What this problem usually is
Diesel fuel system complaints have a pattern of their own. Many are waiting on a recall part that isn't available yet. Others describe the truck stalling or losing power, a fuel smell in the cab, trouble right after refueling, or a diesel particulate filter that keeps clogging. Injector replacement comes up often.
What got replaced
Owners who name the part that was replaced mention the fuel pump (3 reports).

One recall on the fuel system covers the 2020 model year. A recall on the same system isn't always the same failure, so read the defect text.

Is this a known problem?
The manufacturer has sent NHTSA 2 service bulletins or notices for the 2020 Ram 2500 that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

Should you keep driving it?
This page can't tell you that. 1 of 30 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
