Marine fuel pump and cooling system

An integrated fuel system component for use with internal combustion engines, comprising:

• a housing in which is defined a fuel inlet, a fuel outlet, and a plurality of interconnected chambers therebetween, said housing including a vertically aligned cylindrical main body having an upper recess and a lower recess, said main body including an axial bore interconnecting said upper and lower recesses, a fuel reservoir threadedly connected to said main body adjacent said lower recess, said fuel reservoir enclosing said lower recess, and a cover plate secured to said main body adjacent said upper recess, said cover plate enclosing said upper recess and having an axial bore aligned with said main body axial bore;
• a fuel filter mounted in said housing in fluid communication with said fuel inlet;
• a fuel pump mounted in said housing coaxially with said fuel filter, said fuel pump drawing fuel through said fuel filter through said interconnected chambers, and said fuel pump pressurizing said fuel;
• an internal fuel line mounted in said housing for delivering pressurized fuel from said fuel pump to said fuel outlet;
• and
• a fuel cooling system formed integral with said housing, said fuel cooling system circulating a liquid coolant adjacent to said fuel pump, said interconnected chambers, and said internal fuel line.
