Can you remove the fuel pump fuse? I didnt think there was a fuse just for the fuel pump at least it wasnt listed in the manual or owners book..
I have always wondered if you could just change the filter in the morning after the truck has been sitting and not worry about fuel preasure, but each time I have changed it I went into the passengers kick panel, put the end of my torque wrench on the emergency shut off and banged on it lightly. That kicks the emergency switch off and the truck will turn over but wont start, Then you know all preasure has been released..
ALl you need to do is press the switch back in to turn it back on.
