You might even take pictures with your phone before you start for referance. I have to change mine as well, but I'm waiting till I get the pacesetter header.
take the fuel lines off the fuel rail?! I've replaced my exhaust manifold twice on my 2.5L, no need to remove any fuel lines off any fuel rail...
unbolt the 2 bolts off the top of the intake manifold that holds the fuel rail down, pull the fuel rail, then just set to the side, it is flexible, you will have to remove the fuel line from the bottom of the intake, but that is just holding the fuel line in place and requires no special tool or the spilling of fuel or anything, it's 2 bolts, same as the fuel rail tie down bolts, just on the bottom of the intake manifold. I personally had never done it before and one night couldn't sleep, so I tore it apart knowing I was going no where the next day. Did it it a few hours, tearing apart, but I was trying to be respectful to my neighbors since I live in a townhouse, and I also really took my time and labeled everything as it came out (idc how many times I do something, I always label) it gave me something to do (my grandfather had just passed and was also trying to keep my mind busy) next night I put it all back together when I couldn't sleep. It's extremely easy, after doing it one time, I am now confident in saying i can do the swap in 2 hours tops
