FUEL PUMPS

FUEL PUMP

Hytec Automotive fuel pumps, designed for distinguished fuel delivery, easy installation, and proper fit, are compatible with all fuels and additives. Our pumps, manufactured with solid-state worry-free electronics, eliminate vapor lock and flooding. Hytec pumps work well for fuel transfer and make a great stand-alone or booster pump. These self-priming pumps work with a quality engineered two-wire design and only a 12 Volt negative ground system.

DESCRIPTION

A fuel pump is a frequently essential component in a car or other internal combustion engine device. Many engines only require gravity to feed fuel from the fuel tank through a line or hose to the machine. However, in non-gravity feed designs, the fuel tank must pump fuel to the engine, delivering it to the carburetor under low pressure or to the injection system under high pressure. Usually, carbureted engines use low-pressure mechanical pumps mounted outside the fuel tank, whereas fuel-injected engines often use electric fuel pumps mounted inside the fuel tank.

BEHIND THE DESIGN OF AN ELECTRIC FUEL PUMP

The fuel pump is usually electric in multiple modern cars and is located inside the fuel tank. The pump creates positive pressure in the fuel lines, pushing the gasoline to the engine, and higher gasoline pressure raises the boiling point.

Placing the pump in the tank allows the component least likely to handle gasoline vapor well (the pump itself) to be distant from the engine, submersed in cool liquid. Also, it makes it less likely to start a fire. Though electrical components (such as a fuel pump) can spark and ignite fuel vapors, liquid fuel will not explode. Therefore submerging the pump in the tank is one of the safest places to put it.

The fuel pump delivers a constant gasoline flow to the engine, and fuel not used is returned to the tank, reducing the chance of the fuel boiling since it is not that close to the hot engine for too long.

The ignition switch does not carry the power to the fuel pump; instead, it activates a relay to handle the higher current load. It is common for the fuel pump relay to become oxidized and cease functioning, which is more common than the actual fuel pump failing. Modern engines utilize solid-state control, which allows the fuel pressure to be controlled via the pump voltage pulse-width modulation, increasing the pump’s life, allowing a smaller and lighter device to be used, and reducing electrical load.

The fuel sending unit assembly may be a combination of the electric fuel pump, the filter, the strainer, and the electronic device used to measure the amount of fuel in the tank via a float attached to a sensor, which sends data to the dash-mounted fuel gauge. The fuel pump by itself is a relatively inexpensive part. However, a mechanic at a garage might prefer to install the entire unit assembly.
