Removing Injectors from LS - Motorgen - Automotive Events, Meets, Cruises and Forums

Well, I haven't quite found the correct procedure for removing the injectors on an LS motor. How do you make sure there's no fuel in the rails before loosening everything and taking it apart? I've only done this once on a TB and we used a pretty red neck approach, fuel everywhere.

Thakns to kdracer73 again, I done did it. No sissy "relieving pressure"; what's that all about.

It had been sitting for a day so was cold and there was no pressure to speak of. All in all it is pretty self explanatory as I did it and was pretty easy.

However, couple concerns:
1 - On number 8 (which happens to be the problem injector I think) it was either missing the O ring, it bounced somewhere I didn't see when pulling it out, or fell in the runner. I can't see it if it dd. Should I be particularly concerned about this. It's just a little soft rubber, I figure even if it did get dropped in there it would just get burnt up and spit out almost instantly.

2 - A fair amount of fuel came out of the rails, particularly on No. 7, I just let it fall into the intake. It'll probably be at least a week before I get the rebuilt injectors back, so I figure most of that will leak through or evaporate. Should I be concerned? Should I do anything to try and get that fuel out?

on # 2 that shouldn't be a problem at all... fuel will dry up quickly
