The first step in this process is to disconnect the existing fuel line connected to the fuel tank pickup tube; this can be a challenge if you have never done it before as most of the work is done by feel since you cannot see the actual tank module, I have found 2 different ways to get to the feed line pickup, first is to lay under the truck and reach up and on top of the tank you will feel it or if your truck isn’t equipped with wheel well liners then you can go in from inside the wheel well, if you choose this method it will be easier to remove the left rear wheel and support the truck with a rated jack stand for safety. The line you are after is the one toward the rear of the truck as you can see in this picture, notice how the blue retention clip is inside the plastic fuel line connector. The trick here is to squeeze the two tabs together as to release the clip from the shoulders of the pickup tube inlet, squeeze and pull the connector off, the blue retention clip will stay with the pickup tube inlet , then you simply pull the retention clip one side at a time towards you till it actually inverts itself, do this to both halves of the clip and it will slide right off.
