Fuel is moved overboard in most fuel jettison systems by

boost pumps

Fuel jettisoning is usually accomplished

through a common manifold and outlet in each wing.

Fuel jettisoning past the limits prescribed by Federal Aviation Regulations is usually prevented by

dump limit valves or a low-level circuit.

Fuel leaks are usually classified as a stain, a seep, a heavy seep or a running leak. As a general rule;

stains, seeps, and heavy seeps, (in addition to running leaks) are considered flight hazards when located in un-vented areas of the aircraft.

Fuel system components must be bonded and grounded in order to

drain off static charges.

How does temperature affect fuel weight?

Cold fuel is heavier per gallon.

How is the outlet fuel pressure regulated on a submerged, single-speed, centrifugal-type fuel pump

By the pump’s design and internal clearances.

How many engine driven fuel pumps per engine are required for engines requiring fuel pumps?

One fuel pump for each engine.

How many vents, arranged so that they are not likely to become plugged at the same time, must be used in multiengine fuel systems?

Two (2)

How may the antiknock characteristics of a fuel be improved?

By adding a knock inhibitor
