Things To Know About The AirDog Lift Pump

 

The AirDog lift pump is a good upgrade to consider for your car. It can add to your vehicle’s fuel system by helping raise the level of fuel into the engine block by creating suction and managing air flow.

So what exactly does the lift pump do? If functions to raise the level of fuel or other liquid up through a given system. In vehicles, the fuel lift pump works to build pressure or suction in the gas tank, something that encourages the fuel level to rise to the injection systems and on to the engine block. Lift pumps have various applications beyond vehicles and are also used in sewage systems to pump out waste from a full sump pump.

The lift pump should not be confused with a fuel pump. A fuel pump is a mostly essential (older vehicle’s use a gravity system to force fuel into the engine) component of a vehicle’s fuel system. The early versions of fuel pumps used mechanical elements for moving fuel from the gas tank into the carburetor and then on to the engine. This worked primarily as a low pressure system. The modern fuel injection systems changed all that. They electronically create positive pressure from inside the fuel tank so as to force fuel through the system and into the engine block.

So, what are the differences between an AirDog lift pump and a fuel pump? The fuel lift pumps only help in the raising of fuel levels in a given vehicle. They don’t push fuel through the system. The modern fuel injection systems usually come with lift pumps installed with them as well, but they can function without one provided the fuel lines remain airtight, and the fuel injectors are operational.
