Usually when a fuel filter is plugged, there is a lack of power and rarely does it cause stalling. To change the filter you will need special fuel line tools to release the fuel lines from the couplings at the fuel filter, the fuel lines have spring clips that lock them onto the fuel filter. You can buy plastic release tools, but they are difficult to use, aluminum tools are much easier to use and are less likely to damage the fuel line clips. The fuel filter should be mounted on the left frame rail of the truck and the exhaust system is close to the filter, so you should try to change it when the vehicle is cold. There are secondary locks on each fuel line that need to be pried into a release position, then you install the release tool along the fuel filter fitting into the fuel line, as you push the release tool into the line you also push the fuel line towards the filter body, (this takes tension off of the spring lock so that it can release from the fuel line). Once the fuel line tool is full pressed against the fuel line you should be able to twist and pull the fuel line off of the filter,(CAUTION, there maybe residual pressure in the fuel system, so fuel may spray as the line is being removed, might want to cover the line with a rag as you are removing it). Repeat on the other line, then loosen the screw clamp(or spring clamp) that secures the filter to the frame. Make sure you match up the new filter, (some have short fittings and they are not to be installed on vehicle that have long fittings even though they will fit) putting the the wrong filter on will make the next filter change a PAIN. When reinstalling the fuel lines onto the new filter, make sure you hear a click, that is proof the lock is seated, then place the secondary lock on and start the motor. It will take a few seconds to fill the new filter and re-pressurize the system. With the motor running, check for fuel leaks. I hope this helps you. Good luck.
