What kind of airplane would require a fuel pump?
In high-wing aircraft, gravity propels the fuel from tank to carburetor, and fuel pumps might not be necessary. However, a low-wing airplane—and high-wing craft with fuel-injected engines—will need an engine-driven pump to move the fuel.
Does a Cessna 172 need a fuel pump?
The Cessna 172RG is supposedly gravity-fed, but has both an engine-driven and an electrical auxiliary fuel pump, while a regular 172 has neither.
How many fuel pumps does a general aviation plane have?
Aircraft with fuel-pump systems have two fuel pumps. The main pump system is engine driven with an electricallydriven auxiliary pump provided for use in engine starting and in the event the engine pump fails.
How does fuel injection work aviation?
Fuel injected systems use a fuel pump to push fuel through a metering system. Then, the fuel flows through injector lines to each cylinder. Fuel injected systems work a little differently that carbureted engines, because there is no air mixed with the fuel in the metering system.
Will injector cleaner fix a misfire?
Will injector cleaner fix a misfire? If your engine misfires due to unbalanced air to fuel ratio because of clogged fuel injectors, then yes, injector cleaner could clean the clogged fuel injectors and restore the air to fuel ratio.
What kind of fuel pump does a GA plane use?
Most GA planes are configured with either a gravity feed fuel system (like the Cessna 172) or an engine driven fuel pump ( Piper Cherokees) that can be supplemented with an electric fuel pump should it quit or become partially inoperative. The FAA has a nice document on it here (see pump feed systems) their opinion is,
When do you need a fuel pump system?
As you know, a fuel pump system must be used whenever the fuel tanks cannot be installed high enough above the level of the carburetor to take advantage of gravity and the simple, efficient, gravity flow system. Does that infer, then, that a fuel pump system is more complex than a gravity flow system?
What kind of fuel pump does a high wing aircraft use?
Virtually all GA aircraft, high or low wing, use both an engine driven fuel pump and and electric auxiliary fuel pump. Typically high wing GA aircraft will use the aux pump only for priming the engine (fuel injected engines) as gravity feed from the main tanks offers a backup in case of EDP failure.
Can a plane fly without a fuel pump?
Since you claim you can fly with out the pump running we can assume it is an engine pump driven plane however smaller turbine planes that still fall under the GA header may require an electric fuel pump to feed the engine. Virtually all GA aircraft, high or low wing, use both an engine driven fuel pump and and electric auxiliary fuel pump.
