Abstract:
1. A gas and liquid separation device for a motor vehicle fuel tank containing a volatile petrolic liquid fuel and petrolic fuel vapor, comprising: a body having at least one passage therethrough with an inlet configured for fluid communication with the fuel tank and an outlet configured for fuel vapor flow through the outlet; and a separator carried by the body in the at least one passage between and in fluid communication with the inlet and outlet, the separator having a membrane which is semi-permeable or porous with a plurality of pores constructed and arranged to allow the fuel vapor to pass through the membrane to the outlet and block the liquid fuel from passing through the membrane to the outlet and the membrane being inclined at an angle to the horizontal to facilitate runoff of liquid fuel from the membrane when a motor vehicle in which the fuel tank is received is in a normal operating position.
