Oldsmobile Bravada Fuel Pumps
The fuel pump is an essential part of an Oldsmobile Bravadas motor. It is designed to move fuel from the fuel tank to the engine of the vehicle and ensures that an appropriate amount of fuel is being transferred. To choose the right fuel pump, you need to know how Oldsmobile Bravada fuel pumps work and what types of fuel pumps and components are used by the Bravada.
How do fuel pumps work?Fuel pumps come in a number of designs, but most of them work in the same basic manner. They are either mounted in the Oldsmobiles fuel tank, near the fuel tank, or on the vehicles engine. The fuel pump takes in gasoline from the fuel tank and sends an appropriate amount to the engine, where the gas is then combusted. Some fuel pumps are equipped with filtration systems, which ensure that the fuel being used is clean, which therefore protects the transmission. Some fuel pumps also contain sensors that determine the amount of fuel available for intake and the exact amount of fuel that the fuel pump needs to use.
What types of fuel pumps are there?Some older model Oldsmobile cars dont require a fuel pump. Instead, they use gravity to move fuel from the tank to the engine. Vehicles that do require fuel pumps use one of two fuel pump types:
- Mechanical: These fuel pumps, mostly found in older model cars, work using a camshaft or crankshaft. As the shaft moves, it pulls a lever that is connected to a runner diaphragm. The diaphragm acts as the floor of the fuel pump, and when it is pulled down fuel is sucked through a valve into the main chamber of the pump. A spring then pushes the diaphragm back up, which forces fuel through another valve and into the engine.
- Electrical: These types of fuel pumps are often placed directly inside the Bravadas fuel tank and use an electromagnetic switch to move the internal diaphragm. When the electromagnetic switch is activated, it attracts a metal rod at the base of the fuel pumps diaphragm. As the diaphragm moves, fuel is brought into the pump through the intake valve. When the fuel tank chamber is filled with an appropriate amount of fuel, the electromagnet switch is cut off and the diaphragm moves back to its original position, injecting fuel through the exit valve and into the motor along the way.
