ABSTRACT:
A fuel system vapor separator has an outer housing member with a generally cylindrical internal wall and has two open opposed ends. A generally cylindrical inner housing member is fitted within the outer housing member and defines a sealed space between the two housing members. The housing members are sealingly closed at both ends. An inlet introduces fuel into the central region of the inner housing member while another inlet introduces a coolant fluid into the space defined between the outer and inner housing members for cooling the fuel. A float operated valve vents out fuel vapor accumulating within the inner housing member. The housing members are formed by an extrusion process such that they can be cut to various lengths depending upon the desired size of the assembled vapor separator.
