If your  Volvo has a difficult time running , black smoke comes out the tail pipe- that is a sign of ruptured diaphragm inside of 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 .
