This is holding the intake on, how do I get it off? I figured I would ask before I broke something. It is close to the fire wall coming from the passenger side onto the back of the lower half of the intake. Thanks again...

 

This is called a "fuel line". You should be able to press the gray part of the plug in and push the connector off the stainless line. Do not force it!!!! It should come off easy. Just start "squeezeing" that connector and you will figure it out. As I said before......DO NOT FORCE IT!

 

Okay thanks Boris, I'm glad I stopped and took the picture and asked. I (being the blonde I am) was prying on the grey part but decided to stop and ask. Your answer is much appreciated. What if any issues have you had with your 03?

 

The only serious issue I had (that I fixed few months ago) was the oil pump. The outer ring was cracked in 5 different places. Other then that.....regular little things here and there. I made my own tools (harmonic pulley, etc.) so with the help of this forum I manage to tackle all the other little things. At the same time when I did the oil pump I also replaced all the seals and gaskets (except for the head gaskets) on the engine. Took a bit longer than I anticipated but now I feel like I got a new truck again. Changed front engine cover, water pump, timing chain, belts, pullies, tensioner mechanism, etc.
