Trying to change my fuel filter but I can't seem to loosen the nut. Soaked it with PB Blaster and let it sit and still would not budge! any tips?

 

you have to hold it down with a monkey wrench 19 mm and then screw the banjo bolt off, on top and bottom. You cannot just remove the nut without holding the bottom nut, and remember to open the gas tank before you do this to release any air in the system

Be careful you do not want to strip you gas line, and make sure to clean the surrounding area that you used pb blaster in due to its oil content.
