How to Replace the Fuel Pump on a 2000 GMC Yukon


The GMC Yukon is a full-size SUV very similar to the Chevrolet Tahoe. The Yukon XL has a longer wheelbase than the base model, and the Yukon Denali is a luxury version of the Yukon. The most common engine in the 2000 GMC Yukon is an 8-cylinder 5.3-liter engine that uses sequential fuel injection. All versions of this vehicle have an electric fuel pump that supplies fuel to the fuel injection under high pressure.
