    Greetings. I’m getting a low fuel pressure fault and I want to change the fuel pump and accessory drive. There’s a local shop nearby that works on Volvo’s, but it will be more than a week before he can get to it. I’m thinking about tackling it myself this weekend
    About how long should it take to change them?
    Anyone have any tips on what to do and what not to do?
    Any information you can offer will help and be greatly appreciated. Thanks

    it does not but easier to remove accessory and than pump and install first pump than accessory just make sure you do not force anything in, also one of the bolts for the accessory is also holding pump and screwed on from the back.

    I got everything tore apart today. I found some play in the drive and the pump shaft was really worn bad. Can you tell me if the pump bolt holes are open to the oil cavity? I ask this because there was like silicon sealer in the holes as if someone was sealing them from oil.

    they are not open to any oil cavities and whoever put them on before did that not necessary to do and never have done this before.
