EVAP Purge Pump EPP (4/512) [2021-2022]: Description
The EVAP purge pump EPP consists of a plastic housing containing a brushless direct current motor and a radial centrifugal pump, along with internal electronics. The pump transports vapors from the fuel tank to the engine. On engines with low vacuum inside the intake manifold, sufficient purging of the active carbon canister is not possible. The EPP enables purging of vapors by creating a delta pressure between the intake manifold of the engine and the active carbon canister. Vapors enter at the gas inlet of the EPP and are ejected through the gas outlet as the impeller within the pump is rotating. Thus, purging the vapors from the fuel tank.
