If your Volvo has a difficult time running, black smoke comes out of the tailpipe- that is a sign of a ruptured diaphragm inside the fuel pressure regulator. Stalling at idle, - or after running for 10 minutes, - also sign of the fuel pressure regulator that was affected by the fuel with alcohol.
This is an upgrade for the older Volvo that meant to run on gasoline. If you can find gasoline without any alcohol , you are doing great! If you car is running poorly on the stuff that you found at your local gas station, or not running at all and fuel is coming out of the small tube in the center of the pressure regulator when the vacuum line is removed- replace the fuel pressure regulator. The pressure regulator we are offering can handle gasoline with alcohol .
