A diesel exhaust fluid (DEF) delivery system includes a tank for DEF, usually a urea aqueous solution, and a pump receiving the DEF from the tank for pressurization and delivery through a nozzle to the exhaust system of a work machine. A breather assembly is provided for the DEF tank and includes a housing having an inlet for ambient air and a particle filter adjacent the inlet for filtering particles. A hydrophobic membrane is interposed between the particle filter and an outlet leading to the tank for preventing outflow of DEF vapor and condensate.
