Design Features

The Masuma fuel pumps are provided with a high-quality check and bypass valve. The check valve maintains the pressure level in the fuel line after the pump is off and doesn't let the fuel flow down to the tank when the car doesn't move — it facilitates the engine start-up. The bypass (safety) valve protects the pump from overloading in case of the pressure regulator failure; this is also necessary for the cars which are not equipped with a fuel return line.

The technological electronics of the Masuma gasoline pumps ensures high performance and the fuel pressure while has the lowest inner resistance and current consumption.

Graphite Collector

This series of Masuma fuel pumps uses the graphite collector (commutator) for the electric motor. Unlike the copper classics, it's less prone to burn-out and wear-out, ensures better contact with wipers expanding their service life. Moreover, the graphite collector's work is more stable for the use of various fuel types, including high-sulfur cases.

Fuel Strainer

Most Masuma gasoline pumps are supplied with a fuel strainer grid, which you don't need to buy separately. The strainer grid replacement is mandatory during installation of a new gasoline pump.
