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.
