Hi, I'm replacing the valley pan gasket on my 2004 DII. (doing the head gaskets while I'm at it too)..I'm to the removal of the lower intake, no problems, How do I disconnect the fuel line at the rear of the fuel rails. It looks like a green plastic nut..tried just pulling it rearward, twisting it, etc, but just afraid to put too much force on it without knowing how it works..advice from those that have been there is appreciated, thanks, Paul

 

Better down load a free copy of a "RAVE" CD, shop manual.
You will find a link to it in my signature section.

 

Thanks Mike, I have the RAVE and hard copy Bentley, both are silent other than to say disconnect it...I got it off by pulling the green plastic cover forward, the fitting was then uncovered and it had a little arrow showing back and left twist..that removed it. Just removed the right head today...those bolts were torqued beyond belief, No leakage was evident in the head gasket, but plenty in the valley pan...now if I can only get it back together.
