Pulling injectors to send out for cleaning...anything I'm missing?
Headed out of town and figured it was a perfect time to pull my injectors and send them off to Witchhunter. Luckily I can drive the wife's car while mine's sitting in the garage!
Based on reading previous posts and the Clark's write-up, here are my steps...
1. Grab a beer
2. Take off plastic surround of fuel rail
3. Loosen nut on fuel rail to depressurize rail, don't lose ball bearing (I take it the nut doesn't come off?)
4. Wiggle rail, then pull it up and out.
5. Disconnect those funky square clips
6. Pull injectors off rail
7. Bag and pack injectors, mail to Witchhunter.
8. Have another beer.
9. Wait for schwank, have another beer.
10. Have beer with schwank.

1. Grab a beer
+1
2. Take off plastic surround of fuel rail
+1 Take extra care to not break any of the plastic clips.
3. Loosen nut on fuel rail to depressurize rail, don't lose ball bearing (I take it the nut doesn't come off?)
No need to take the nut off (BTW it does come off all the way but it requires some force to initially remove it and you may damage your fuel rail trying).
Just remove the fuel pump relay and turn the engine over to depresurize the system. Either way make sure you have some rags handy to catch fuel spillage and don't do it with the engine hot.
4. Wiggle rail, then pull it up and out.
+1, sometimes requires more than a wiggle.
5. Disconnect those funky square clips
+1 if they are still fitted. They are sometimes forgotten and really not required, so people leave them off.
6. Pull injectors off rail
+1
7. Bag and pack injectors, mail to Witchhunter.
+1
8. Have another beer.

9. Wait for schwank, have another beer.

So if I pull the relay I burn the fuel in the lines off, then she dies, then I skip straight to pulling the rail...interesting.
Didn't drive the car today and therefore am not worried about the engine being hot.

Yep, or you can pull fuel pump fuse #34 with the engine running and wait til it dies.

1. Grab a beer
Yep
2. Take off plastic surround of fuel rail
Why? If all your doing is removing injectors I don't see why you would do this and I don't recall ever doing it for any reason.
3. Loosen nut on fuel rail to depressurize rail, don't lose ball bearing (I take it the nut doesn't come off?)
Like the other guy said, pull fuel pump fuse #34 with the engine running and wait til it dies. Usually a good idea to disconnect the battery at this point.
4. Wiggle rail, then pull it up and out.
Might have to wiggle really hard if you don't remove the four 10mm bolts holding the rail to the cam tower (2) and intake manifold (2). I would remove these first! Unless the early rails are different you should have these.
5. Disconnect those funky square clips
At this point I would remove the electrical connectors from each of the injector and then remove the square clips.
6. Pull injectors off rail
Yep, and be ready for some fuel spillage
7. Bag and pack injectors, mail to Witchhunter.
8. Have another beer.
9. Wait for schwank, have another beer.
10. Have beer with schwank.

I would add; Make sure you completely remove your spark plug wires and make sure they're clear of the rail before you yank it out. I ripped out my #2 wire from the sudden release of the injectors from the intake.

Just got mine back from WitchHunter. I sent them out Priority mail last Thursday, and got them back the following Wednesday (yesterday). Really fast turnaround. I prepped, taped, and painted them last night, and they're ready to install today, just a week after I sent them.

Wow, not even a 1 beer job... Just wasn't expecting quite that much fuel to come out. I'll have to remember to go out and grab all those soaked rags this evening...
