How to Check the Fuel Lines and Fuel Pump on a Subaru Outback


Two things make an internal combustion engine function: fuel and fire. If the engine in an Outback isn’t working the way it should, then it’s because there’s a restriction on one or the other. If it’s fuel, then the two most common problems are a clogged fuel filter and a malfunctioning fuel pump. Check the filter for clogs, and then check the pump and fuel lines.

Tools Used: Tools, Floor jack, Jack stands, Replacement parts, Clean bucket, Adjustable wrench

Check the Fuel Lines and Fuel Pump

Lift the rear end of the Outback with a floor jack, and support it by the frame with jack stands. Locate the fuel tank centered beneath the rear hatch and the fuel lines running from the gas tank along the bottom of the station wagon to the engine compartment. Examine the fuel lines for any kinks, crushed areas and dents.
