Filter 1 is on the driver side of the engine mounted to the block. You will need a 29mm socket to undo this. You will also likely need a elbow or 2 to get around the hood cowl. Note the cap is plastic so take care not to strip it.
Filter 2 is located just in front of the Rear Axel centered above the drive shaft. This filter is a screw on filter.
** please note that you will get a good amount of fuel spillage when you unscrew this filter. Ensure your eyes are not going to be leaked on.
Note the water in fuel sensor / drain. this sensor can be unplugged from the truck harness to make removal easier.
The Part number for this is PFRK54553 but you dont need to replace unless damaged. a new o-ring comes with the filter.
