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 injection system. Often, carbureted engines use low pressure mechanical pumps that are mounted outside the fuel tank, whereas fuel injected engines often use electric fuel pumps that are mounted inside the fuel tank (and some fuel injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine).

Then there's a twenty on the oxygen fuel pump, and a pair of twenties on the fuel-tank charging motors.
Only about half of the old suppliers are still in business, so we had to find new approved suppliers, for the heat exchanger duct assembly, the lox mating ring, the fuel pump housing, the pump housing machining.
For higher pressure, but a somewhat lower volume, you could use an electric fuel pump.
Using refined fuel in this supplemental tank requires less than one percent of the total fuel supply for the newer vehicle and keeps the fuel pump and filter full of refined fuel when the equipment is shut off.
The fuel pump wheezed loudly, telling of a break in the diaphragm, but gas squirted out the end of the hose and dribbled into the tube.
The storage compartment held a grand total of three wrenches of various sizes, a screwdriver, a fuel pump, four spark plugs, assorted nuts and bolts, a couple of rags, a wooden paddle, a nylon boat cover and a handy-dandy little number that's going to add to the enjoyment of the voyage.
