I am sure the left side hose is at the bottom of the tank. I more think the pump is shutting off after sometime of driving...So that would lead to a faulty CEM module as I can watch the left side with the car at idle and the level is okay. At some point the left side stops working while driving and ...

Also carry the fuel rail pressure sensor.

The complete unit with hose was changed. Then there two pumps in the right hand assembly... We see the North American versions.

Guys am new to this Volvo. The right side of the fuel tank keeps going empty and the car would shutdown. A new fuel pump assembly have been installed with the same problem. Any theory of operation or assistance is appreciated.
