Hello,

We have a 2005 Volvo S60 and have been having trouble with the fuel system.

We had a check engine light on and the code was for the fuel filter or fuel pump. The car eventually started to turn off on its own while driving. We took it to a shop and they replaced the fuel pump and fuel pressure sensor. About 50 miles later the check engine light went on again with code P0191.

It looks like the only thing left to replace is the Fuel Pressure Regulator. I cannot find a location via the internet nor could I find one while searching the forum.

Also, we could not locate the fuel filter. The mechanic said it was in the fuel pump. But I understand it to be a screen. If there is one outside the fuel pump, help with that location is helpful too. We found directions to look under the car toward the rear tire, but, there's nothing there.

Any help is appreciated! (Pictures prefered )

Thank you!!

 

There is no regulator and if you have a steel fuel tank, no filter either.

 

Okay, thank you.

If neither of those exist in my car and we already replaced the fuel pump and the fuel pressure sensor. What could be the problem??

 

Could be the fuel pump control module
