That's for the Cummins. The gas engine only has a filter built into the fuel pump in the tank. If it's running fine then it's nothing to worry about

Is there a chemical way of cleaning the fuel system?, reason is engine on and off spits and sputters and then it dies and won't kick over until it sits for awhile like it would from a clogged fuel filter

No codes, no check engine light, it's a 2019, I'm checking about the warranty
