I checked Hyundai WebTech to get some tips on replacing my fuel filter. Is it really necessary to disconnect the fuel pump? I just don't feel like ripping my rear seat out to gain access. How much pressure is it under while the car is off? If I just put a rag over the "in" tube will that be enough to cover the spray, or should I really disconnect the pump first and stall the engine out to release all the pressure?
