How to Check the Fuel Lines and Fuel Pump on a Toyota Tundra


Two things make an internal combustion engine function: fuel and fire. If the engine in a Tundra isn’t working the way it should be, 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 Tundra with a floor jack, and support it by the frame with jack stands. Slide under the back end of the truck. Locate the fuel tank, which is a large tank centered under the bed. Find the fuel pump bolted to the front of the tank and the fuel lines running from the pump to the engine compartment. Examine the fuel lines for crushed or kinked areas.
