It's not all the time that you find yourself in need of a replacement Fuel Sending Unit to fix your automobile. When your Buick Rainier left the factory, it was destined for a person with discerning taste who wants economical pricing in their automobile. You bought your Rainier because its reliability and a trusted name struck a chord inside you; so why would you settle for second rate when it comes to great quality auto parts? While it's not hard to find replacement parts for Buick vehicles, these days only the absolute best are required to repair your automobile.
You can't get great gas mileage and horsepower at the same time without high quality engine components. Located inside the gas tank is your Buick Rainier fuel sending. The fuel sending unit will have an outlet pipe on it to service the demands of the fuel pump, and should there be any excess fuel in the carburetor or accumulator a return pipe will be there to take it back to the tank. All fuel sending units have a float attached to an arm on the unit that goes up and down as the amount of fuel in the tank changes. That articulating arm is connected to a resistor that changes its strength based on the position of the float; modulating the signal that tells your Buick Rainier fuel gauge how much fuel remains in the tank.
