Fuel filter and fuel rail codes
i've had my truck for over a year now (2009 chev duramax) When I push the truck hard either passing someone/race or towing my boat I get 1 of 2 codes that come up I either get change fuel filter (which isn't close to needing a change) or I get a fuel rail code. My truck has H&S Minimaxx tuner, cold air and Flopro Exhaust front to back duel and delete. All my fuel lines look fine no colapsed or kinked lines. Is my truck just demanding to much fuel and running the filter dry? Would I be needing a lift pump to feed the demand?
