So the owner's manual suggests you change the fuel filter every 30,000 miles for my 05. I'm currently at 59,7xx miles and as I bought the truck used, have no clue as to when the previous owner changed the filter, if they did at all. I'm planning on changing it and want to do it myself, but as instead of being in the engine compartment as I've only had experience with (carbuerated engines), it's right after the fuel tank and you have to disconnect the fuel lines to change it. So my question is, do you recommend a dealer changing it, or can someone tell me the proper way to change it so I don't f*** my fuel system.
