How to remove the Fuel Tank on Buick LaCrosse?

To remove the fuel tank, start by relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. Then, raise the vehicle and secure it on jackstands. If applicable, remove the left and right rear underbody air deflectors. It is also recommended to remove the part of the exhaust system underneath the fuel tank for easier lowering. Next, disconnect the fuel tank filler hose and the fuel feed, fuel return, and EVAP vent line quick-connect fittings. On newer models, remove the fasteners from the front of the right-rear inner fender splash shield and unplug the electrical connector for the fuel pump module wiring harness. Support the fuel tank with a floor jack and remove the bolts from the non-hinged end of the longitudinal straps that support the tank. Carefully lower the tank to access the fuel pump/fuel level sensor module and disconnect the fuel line quick-connect fitting and electrical connectors. Finally, lower the tank completely. To install, simply reverse the removal steps.

Buick LaCrosse Fuel Tank

The Fuel Tank in your Buick LaCrosse stores gasoline safely and feeds it steadily to the engine. Hence, it is essential for the sedan's everyday reliability. Within the Fuel Tank, an electric fuel pump and gauge sender are placed submerged. Internal baffles stop sloshing so the pump pickup remains covered even during sharp turns or hard stops. The Fuel Tank also assists in sealing harmful fuel vapors in the EVAP system to reduce emissions. Buick engineers have relied on two basic construction styles over the years: stamped and welded steel or blow molded high density polyethylene, engineered to withstand rain, salt, and road debris under the car. The steel Fuel Tanks resist impact well, yet can rust on the inside and outside. The plastic ones won't rust, but do crack from extreme heat, cold, or vibration. Every factory Fuel Tank is pressure tested for leaks, then delivered with a fresh locking ring and seal. Each LaCrosse has sturdy mounting straps that keep the Fuel Tank securely in place. Regardless of how different their designs may be, Buick drivers can expect dependable range, accurate level readings, and quiet operation from the LaCrosse Fuel Tank.

Each OEM Buick LaCrosse Fuel Tank we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
