Hi, where is the fuel pressure regulator located on a 1995, 1.8 petrol, Volvo 460 and how do I replace it? Thanks in advance 
Your '95 Volvo should have the SPi (single point injection) Renault engine. If you take the plastic air duct off that sits on top of the injector (3 bolts), you'll see the injector body. It looks very much like a carburettor. As you look down, you'll see the throttle body opening, and a round item directly in front of it with the fuel flow & return pipes leading away towards the passenger side of the car. This round bit is the fuel pressure regulator.
Replacement should be self explanatory if you have a new one to look at, but you'll need to depressurise the fuel system first - pull the fuel pump fuse with the engine running until it stalls. It's best to remove the injector body from the car to work on it.
