fuel pump application

In many modern cars the fuel pump is usually electric and located inside the fuel tank. The pump creates positive pressure in the fuel lines, pushing the gasoline to the engine. The higher gasoline pressure raises the boiling point. Placing the pump in the tank puts the component least likely to handle gasoline vapor well (the pump itself) farthest from the engine, submersed in cool liquid. Another benefit to placing the pump inside the tank is that it is 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 (see flammability limit) and therefore submerging the pump in the tank is one of the safest places to put it. In most cars, the fuel pump delivers a constant flow of gasoline to the engine; fuel not used is returned to the tank. This further reduces the chance of the fuel boiling, since it is never kept close to the hot engine for too long.
Fuel pumps are usually replaced for two reasons—to restore OE functionality in the event of low fuel pressure or fuel pump failure, or to increase fuel pressure and volume as required by high performance applications. MYH stocks a complete line of OEM direct replacement fuel pumps as well as performance pumps, both intank and external, designed for gasoline, diesel, or E85.
