Unfortunately, I don't have a pressure tester and am working alone, so I kind of have to throw parts at the car. I just bought (from Parts shop) and installed a new "fuel accumulator," which I thought was the pressure regulator. Now I see that there is a real pressure regulator listed under fuel injection instead of fuel delivery.
Question: Is this a part to simply replace or is there any cleaning or adjustment on it? It costs a lot of $.
Exactly where is it located on the engine? There is no photo of it in the parts listing.
