air pump on 2001 Chevrolet Impala

my impala air pump keeps sucking fliuds up and can not figure out why

Asked by for the 2001 Chevrolet Impala
what kind of fluids? this is an electric pump and isn't exposed to any liquids, maybe if the checkvalve is bad it is allowing condensation from exhaust to get to pump, but give me some more details of your problem so i can better respond-thanks
