One problem related to fuel filter has been reported for the 2020 Ford F-450. The most recently reported issues are listed below.
Kept smelling faint diesel fuel odor would come and go while driving for 11,000 miles, never saw a leak, then became worse and saw drops on driveway size of a dime. Found a steady drip of fuel only while running from fuel filter under hood above valve cover, replaced filter and leak stopped. Closer look found heavy stains from fuel leak on top of engine. Has been that way since new. Leak now fixed. This could be a fire hazard. Glad I found it.
