Feed your engine with the Saturn fuel pump

Saturn’s mission, philosophy and values are all directed toward recapturing new customers and achieving world-class levels of quality and customer enthusiasm. Armed with these goals, Saturn has produced cars specially designed to meet, if not to exceed standards of quality. But no matter how well-made a car may be, its parts still need maintenance in order to function well.

In order for humans to actually live, they need food. When it comes to cars, they need fuel in order to function. But how does the fuel goes to the engine for consumption?

In order for the fuel to go the engine, it needs to be pumped from the fuel tank. This is done with the help of the Saturn fuel pump. The Saturn fuel pump is an essential component on a car or other internal combustion engined device. Fuel has to be pumped from the fuel tank to the engine and delivered under low pressure to the carburetor or under high pressure to the fuel injection system. Some fuel injected engines have two fuel pumps for this purpose: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine.

The absence of electricity during the 1970's required fuel pumps to be bolted to the engines and driven mechanically by a lobe in the camshaft of the engine. This usually caused vapor lock, a problem that results when the pump couldn't pump out more gasoline to the engine so it eventually cuts out. This is usually caused by the boiling of the gasoline due to the negative pressure from the pump plus the engine heat or hot weather. Electric fuel pumps, however, are the most commonly used nowadays. Moreover, Saturn fuel pumps are now located inside the fuel tank. This is primarily done to prevent the start of a fire and fuel boiling. Since liquid fuel does not explode, it is deemed safe to submerge the pump in the tank.

It is advised that a Saturn car should not run it when it is already out of gasoline because this will burn up the Saturn fuel pump in a short period of time. A common indicator of a Saturn fuel pump failure is loud humming noise in the engine. But more importantly, Saturn fuel pumps fail without warning so it's a must to keep it properly maintained at all time.
