How does the fuel system work on an airplane?
The fuel delivery system includes fuel tanks and fuel lines, any fuel pumps necessary to move the fuel from the tanks to the engine, fuel strainers to prevent contaminated fuel entering the engine, a set of valves and vents to control the movement and pressure in the system, and a set of fuel level sensors and cockpit gauges.
What happens if you have air in the fuel line?
If the fuel tank was empty, the fuel line dry and you subsequently added sufficient fuel, the engine would start after the air was purged from the fuel line and fuel was flowing through the injectors. As long as the fuel pump pickup remains submerged in fuel there is zero chance of air getting mixed with the fuel.
When to replace an air fuel ratio sensor?
If you notice a decrease in fuel efficiency or engine power output, as well as a rough idle, you may have to replace any air-fuel ratio sensors. 1. Decrease in fuel efficiency
How does a low wing aircraft fuel system work?
Low wing aircraft with wing mounted tanks require a pump to move the fuel from the tanks to the carburetor or injectors. A system dependent on a pump to feed the engines requires a certain level of redundancy in the form of a primary main pump and a backup auxiliary pump.
How to bleed air out of the fuel system?
Open the left screw at the top (10mm wrench) a few turns and wait for fuel to run out. Once there are no more bubbles coming out tighten screw back up and repeat with the screw on the right. This will indicate that the filter is full of fuel.

How did the FAA change the way planes were built?
The FAA subsequently mandated that aircraft lavatories be equipped with smoke detectors and automatic fire extinguishers. Within five years, all jetliners were retrofitted with fire-blocking layers on seat cushions and floor lighting to lead passengers to exits in dense smoke. Planes built after 1988 have more flame-resistant interior materials.
What causes air to be trapped in a diesel filter?
When you change a diesel fuel filter, run out of fuel or disturb the fuel system, air is trapped. When you try to start the engine this air acts as a lock, preventing the normal supply of fuel.
