Thanks everyone what I thought was obvious and already done I shouldn't assume. I will start with the fuel filter and go on from there. On Youtube they show removing the inner fenderwell to access the filter is there any other way?
Here is how I change mine.
I grab a 1 gallon zip lock freezer bag from the pantry. Proceed out to truck.
Unplug the water in fuel harness.
Place zip lock bag around the filter and remove.
The bag is strong enough to hold the filter and the fuel and it won't leak every where.
Seal up the zip lock, this keeps everything in the bag and you can maneuver it out and around all the crap.
Once you have it out of the engine compartment remove the water in fuel sensor, clean it up, and install on new filter.
Twist new filter on, hand tighten only, if you over tighten it you will end up cracking the housing it screws onto, and you will suck air in through the crack, and most likely will not see the crack. I have replaced a few on friends trucks.
