We have taken the mystery out of automotive service jargon, so that you don't have to.


Fuel Pump

A pump that draws gasoline from the fuel tank to either the carburetor or fuel injectors. While these can fail slowly, typically they work or they don't. Changing them is also no fun, as they are usually located in the fuel tank. Good times right there.
