Fuel pump Wikipedia
A fuel pump is a frequently (but not always) essential component on a car or other internal combustion engined device. Many engines (older motorcycle engines in particular) do not require any fuel pump at all, requiring only gravity to feed fuel from the fuel tank or under high pressure to the fuel
3 Common Mechanical Fuel Pump Problems
Most mechanical fuel pumps have a weep hole on the bottom of the unit. When the internal diaphragm leaks, fuel escapes through the weep hole to notify the vehicle owner of a malfunction. This is one of the more common fuel pump problems found in classic cars that are between 30 and 60 years old.
Testing Golf Cart Fuel Pumps
The fuel pump has several nozzles on it to accept the vacuum line, and both the Fuel In and Fuel Out lines. Inside the pump, there are several diaphragms which use the pulsing action created by the vacuum of the crankcase pressure to draw fuel from the storage tank and push it onward to the carburetor of the golf cart. The fuel nozzles as well as vacuum line connections are shown below.
How a fuel pump works How a Car Works
A fuel pump draws petrol out of the tank through a pipe to the carburettor.
