George,<br><br>For the first time you should probably count on about 2 hours, but with practice you'll swap 'em in 45 mins.<br><br>John

George, <br>With a 2003 there is extra work to do while changing injectors.<br>Its probably going to run 3 hours.<br>You have to remove the exhaust rockers, and also the rocker housing, wires etc.<br><br>--Justin

Good call Justin... I didn't notice the 2003 :P

I have asked several people that install them and four hours was the estimate I got from all of them. They also all agreed that part of that time was just from going slow and careful because a booboo can be pretty costly with the 03 and they are easier to have a booboo with. I dont know if your aware of the core shortage but in my area you have 2 options. One is you can have em pull your injectors and rush em down to get done and rushed back which leaves your truck down for 3 days or use a core that in my area is being shared between 8 shops and there is a two week waiting list for that here. Im going to do the rush option.

On a 2002, how the heck do you get to the one in the back? I ain't as flexible as I used to be :

Removing the rear lifting eye gives a lot more room to get in there. Two bolts hold it in. Besides that... Go Go Gadget Arms....<br><br>John

Injector swaps are pretty easy in 03's.

Here are some directions:

1.Remove plastic vanity cover
2.Remove hoses from breather bottle on top of valve cover.
3.Remove Valve Cover, Remove intake arm and grid heater.
4.Remove wire harness connections from rail and combo sensors, also remove injector harness connections (3 on the side of rocker box)
5.Loosen and remove all injector wires from each injector.
6.Remove rocker box (mide piece between vc and head).
7.Completely loosen all injector lines at the head, next remove bleed off banjo from top of rail
8.Remove rail feed line from CP3 fuel pump.
9.Next remove securing bolts for common rail and securing bolts for fuel lines, this will allow you to remove the common rail with all fuel lines attached.
10.Remove all male connector securing nuts and pull male connectors out enough to allow injector removal.
11.Number each Exhaust rocker, remove each exhaust rocker (sometimes it maybe necessary to bar over or remove intake rocker to swap an injector), do not loosen adjustment nut.
12.Remove all injector securing bolts.
13.Next pull out injectors.

Torque specs:
Injector securing bolt: 8mm 10nm
Injector wire nut: 8mm 1.25nm (thats extremely light) Be very careful here, if you break off the copper stud on the injector, you'll be having a very bad day!)
Rocker: 10mm 34nm +/- 2nm
Male connector nut 24mm 50nm
Fuel lines: 19mm 29-31nm
Intake arm 10mm 24nm
Rocker box bolts 10mm 24nm
Valve cover and vanity cover bolts 10mm 24nm
Fuel line and rail securing bolts 10mm 24nm
Remember the Yellow and Brown wire nuts always will be closest to the intake side or rocker.

Be careful to isolate fuel system components to keep debris out of system.
