Hey Guys!!! I can't stand trucks behavior replacing COP.
I have huge hands can't get COP off so I am taken the fuel rail off!! YES ITS THE ONE IN THE BACK #8!!!! HAAAA!!


So tell me I shut the fuel off then unplug battery then bolts on fuel rail then pull fuel rail off?

What is the proper way to shut fuel off?

Can someone post a step by step?

Thanks guys!!!

wow, makes it sound simple... almost. It reads like stereo instructions...lol. Good stuff though.

Thanks Guys...

Question: why drain coolaint?

Thanks for your help..

cory-burt

to maek it easier the instructions say to disconnect some of the coolant lines, i'm assuming its just to keep it from making a mess when they are disconnected

1. Pop the hood
2. Disconnect battery
3. Go inside the truck shut fuel off on the pass side
4. Undo each bolt, two on each side holding the fuel rail on
5. Pull up on the fuel rail
6. Plug fuel rail holes with cotten or cloth to prevent gas leaking out
---
Cop
1. unplug elec. connection on COP
2. undo bolt
3. pull out cop
clean and replace with new ones

Did I miss anything?

Cory-burt's instructions are for REPLACING the fuel rails, not simply removing them for the purpose of easier COP/plug handling nor are they for simply replacing the injectors. In addition to your 1-6 I would replace the o-rings and use di-electric grease to put the injectors back if you remove them.

Are there any tricks to putting the fuel rail back on? I needed to get to #7 to remove the COP and spark plug, so I pulled the rail off, but it doesn't seem to want to go back on. I didn't release the fuel pressure, I just pulled on them and pulled them off. I lost a little bit of fuel but not too much. I aligned them back up with the injectors (which I didn't remove) and tried to push down and pop them back on, but they don't seem to want to pop back on.

I have large hands myself. Find a 7mm with with built on swivel. you can do it with out pulling the rails.

Take the pressure off..
