Truck Repair: Volvo bin truck

Question
I have a 1995 Volvo bin truck. I need to replace the fuel pump. Have the part but can't find a manual. I need info on how to change it as I know there are technicalities regarding timing and bleeding.

Answer
Not sure what a bin truck is but on the Volvo semi trucks it has a long short shaft that engages in the gear in the timing cover. If that's the same pump there's no timing to it just pull out the old one and make sure when you put the new one in that it engages the gear and the pump sits flush with the cover.
