context_page_description: The Ford Model T used a 177 cu in inline 4-cylinder engine. It was primarily a gasoline engine. It produced 20 hp for a top speed of 45 mph. It was built in-unit with the Model T's novel transmission, sharing the same lubricating oil.
  The T engine was known for its simplicity, reliability, and economy. The engine remained in production for many years, and millions of units were produced. The engine design's lifespan exceeded that of the Model T vehicle itself, with industrial, marine, and military applications extending its production run. The T engine is on the Ward's 10 Best Engines of the 20th Century list.
context_section_description: The T engine had one carburetor, a side-draft, single-venturi unit. Its choke and throttle valves were controlled manually; the latter was with a hand lever rather than a foot pedal. The carburetor had no accelerator pump. Various vendors supplied Ford with carburetors for the T engine, including Holley, Zenith, and Kingston. 
  During most of the T's production run, its 10 gal fuel tank was mounted to the frame beneath the front seat. Because Ford relied on gravity to feed fuel to the carburetor rather than a fuel pump, a Model T could not climb a steep hill when the fuel level was low. The immediate solution was to climb steep hills in reverse. In 1926, the fuel tank was moved forward and upward, under the cowl, on most models, which improved the gravity feed.
