Fuel Rail Removal 850

posted by  someone claiming to be Ted Forne on  Fri Apr 2 12:37 CST 2004 [RELATED]

I have the oh-so-hated Chilton repair manual and it seems lacking in the instructions department. I'm attempting to change my fuel pressure regulator, and I can't seem to get the fuel rail off. I've taken off a piece that connects to the fuel rail, that I thought was part of the fuel rail but is only the top cover. I've also disconnected the tube that connects to the fuel pressure regulator. The throttle body cover is off. I unscrewed a torx screw from the passenger side of the fuel rail that seems to be a useless screw, but I'm sure is good for something, along with some kind of weird spacer. Now I'm left with the injectors. I can unclip the tops, but something seems to be holding the fuel rail on and I can't tell what it is. I don't want to break anything! Can someone please help?

    ted,
    slow down !! to remove the injector rail on an 850 all you have to do is remove the cover you spoke of and two 6mm,10mm head bolts holding the rail to the manifold then two torx screws holding fuel lines to top of engine and one more 6mm bolt low on the firewall side holding the fuel lines again. the injector rail is very tight and needs a good yank .......oh almost forgot on top of the injectors there are seals, they look like flattened out o-rings whan you pull on the rail it may seperate from the injectors.... don't loose these things! if the injectors are the stuck in the head use a twisting motion and lots of muscle... volvo supplies their dealers with a set of clamps in order to remove the entire rail as one piece. good luck and let me know how you do on this ......good luck
