In years past, I've heard cussing and discussing on this subject from many who have worked on them. Mostly concluding that you should avoid touching them, like the plague.
However, I now have my engine disassembled and my fuel rails are in tact, on the shelf, waiting to go back on the engine.
I am concerned, because when I was dismanteling them from the intake, the small "O" rings on the tips of the fuel rail inlet and outlet tubes, where they attach to the chassis tubing, were in BAAADDDD shape, looking like a couple of dried up fishing worms.
I would feel better if I could change all of them at all the cross tubing connections and all, but the old stores of woe are keeping me from it.
Are these a real problem or could most reasonably compotent mechanics
accomplish the task with minimal difficulty???
Thanks to the info you all provided, I stoped by Autozone last night. To my supprise, they had them. A boxed set of "O"-rings called a fuel rail seal kit. They actually had 3 items called a fuel rail seal kit. one added the word "INNER" and one the Word "OUTTER". After loking them over, I decided the correct one was the one with neither word. The Cost??? $2.99!!!
