Hey guys this may sound stupid so have your fun now and laugh but is there an easy way to change the fuel filter. Is there a special wrench to get down there or is it easier to unbolt and unhose the filter from the truck and unscrew the filter outside the truck. I am very new to this and was very frustrated last friday when the thing gelled up on the way to work, lol. Please any suggestions or tips from all you pros? Also how often should I change all these filters on the truck, My dealer so far has not provided the manual for the diesel section so....
