The impact tube pressure is connected to "Chamber B" on the side of the air metering diaphragm farthest from the carburetor body. As the air pressure in chamber B is increased, the diaphragm is moved toward the carburetor body. [14] The difference in pressure between chambers A and B creates what is known as the air metering force'. [14]
Holley Brothers Company advertisement for carburetors in the Automobile Trade Journal, 1916.. Holley's history starts in Bradford, Pennsylvania, in 1896 when teenage brothers George (1878–1963) and Earl Holley built a small, one-cylinder, three-wheeled vehicle they dubbed the "Runabout", with a top speed of 30 mph.

The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion (see stoichiometry) and influence the advance or retard of ignition timing. A fuel-injected engine may alternatively use a mass airflow sensor (MAF sensor) to detect the intake airflow.
The Ford MEL is a big-block 90° V8 engine family produced in various configurations by the Ford Motor Company between 1958 and 1967 in displacements from 383–462 cubic inches (6.3–7.6 L), and used in Ford, Edsel, Mercury, and Lincoln vehicles.
