Hi again,
Just got my replacement fuel injectors (Thanks Gary). I also purchased 4 new seal kits.

Before I go breaking the injectors - what is the best way to get the end cap, o-ring, and plastic ring off the injector to put on the new stuff.

thanks

well, now that I have the ic, tb, and upper intake off I can see that the supply line is soaked right below the pulse dampener. Do I just need to replace o-rings or will the entire fitting/hose need to be replaced?

Sounds like you need to check more than the injectors. I have heard of pulse dampners leaking. You will need to determing exactly what it is that is leaking

Well, I've found replacement o-rings for the connection at the dampener, and I know at least one injector was leaking. If it's not fixed completely there should at least be a significant improvement.
Plus, I need my car running.
If I find there is still a leak at the dampener I can replace it later if I need to. It only took about a half hour to get it disassembled.

Any leak at all is a fire hazard. I would urge you to make sure it's fixed before you drive. Perhaps seeing if you can arrange someother form of transportation. We have had more than one person here with car fires caused by fuel leaks

Fuel odor is gone.
There was a slight odor on the first test drive and the shrader valve had some fuel (maybe solvent) sitting in the valve itself and I was concerned about a leak there. Today it was dry and I haven't noticed any problems since so I think there may have been some left over fuel or solvent that had collected there during the job.
