- Summary
- Be aware that fuel lines are color coded on vehicles with return fuel pressure lines. The black line is for fuel pressure supply and the blue line is for fuel pressure return. To verify correct line installation, remove the metal cover exposing the fuel pump flange assembly (generally under the rear seat). Refer to the ELSA Repair Manual for specific location. Check for raised arrows on the flange housing. The black line (Fuel Pressure Supply) attaches to the connection with the arrow pointing away from it. The blue line (fuel return) attaches to the connection with arrow pointing to it.
