Changed the Fuel Pressure Regulator in the 2000 s40 tonight. Everything went well with one exception. BE CAREFUL IF YOU RELIEVE THE FUEL PRESSURE THROUGH THE VALVE AT THE END OF THE FUEL RAIL, IT CAN SPRAY INTO YOUR EYE!! Now that may seem like common sense, and maybe it is, lol, but I never considered it shooting gasoline 5 feet into the air. I ended up using a rag over the valve and the depressing it. Just wanted people to know.
