Float bowl attachment for carburetor

A carburetor float bowl for use in a fuel system, said fuel system having a fuel supply, a throttle linkage, and a fuel carburetor with a metering block having fuel passages therethrough, said float bowl comprising:

• a body having a peripheral wall, an open end, a closed end opposite said open end, and an interior volume bounded by said peripheral wall, and said open and closed ends;
• first and second fuel passages through said body, each of said first and second fuel passages having an inlet end coupleable to the fuel supply and a discharge end communicating with said interior volume;
• first and second valves, each respectively disposed in said first and second fuel passages to selectively close said respective fuel passages;
• and
• first and second floats, disposed in said interior volume, respectively operatively coupled to said first and second valves, each of said floats being mounted to said body for movement between a closed position in which said floats close said respective valves and an open position in which said respective valves are permitted to open said respective fuel passages, wherein said first and second valves are operated substantially identical such that said first valve is one of opened and closed in a first amount and said second valve is one of opened and closed in a second amount, which is the same as said first amount,
• said float bowl being adapted for mounting on the metering block with said open end of said body being configured for sealing engagement with the metering block, and said interior volume being configured to communicate with the metering block's fuel passages.

An attachment for a fuel system, the fuel system including a carburetor, a metering block capable of being coupled to the carburetor, and a fuel pump in fluid communication with the attachment, the attachment comprising:

• a first housing defining a first fluid chamber and having a first end with a first opening and a second end with a second opening opposing said first end, said first housing including a first fluid inlet in fluid communication with the fuel pump and said first fluid chamber, wherein fuel flow through said first fluid inlet is controlled by a first regulator disposed in said first fluid chamber and said first end of said first housing is attached to the metering block;
• a second housing defining a second fluid chamber and having a third end with a third opening and a fourth end with a fourth opening opposing said third end, said second housing including a second fluid inlet in fluid communication with the fuel pump and said second fluid chamber, wherein fuel flow through said second fluid inlet is controlled by a second regulator disposed in said second fluid chamber and said third end is attached to said second end of said first housing, whereby said first and second fuel chambers are in fluid communication;
• and
• a cover disposed on said fourth end of said second housing for closing said fourth end, wherein said first and second housings are capable of storing fuel in said first and second fuel chambers at a predetermined fuel level.

A carburetor assembly, comprising:

• a carburetor main body having a fuel vapor intake;
• a fuel regulator connected to said carburetor main body and having a fuel vapor outlet and a fuel intake, wherein said fuel vapor outlet is in fluid communication with said fuel vapor intake of said carburetor main body;
• a fuel supply assembly connected to said fuel regulator defining an interior fuel chamber for storing fuel at a fuel level, including,
• a first housing defining a first portion of said interior fuel chamber and having a first side with a first opening attached to said fuel regulator and a second side with a second opening, wherein said first housing includes a first fuel inlet passing through said housing and in fluid communication with said first portion of said interior fuel chamber, and a first regulator coupled to said first fuel inlet for controlling fuel flow through said first fuel inlet;
• a second housing defining a second portion of said interior fuel chamber and having a third side with a third opening attached to said second side of said first housing and a fourth side with a fourth opening, wherein said second housing includes a second fuel inlet passing through said housing and in fluid communication with said second portion of said interior fuel chamber, and a second regulator coupled to said second fuel inlet for controlling fuel flow through said second fuel inlet;
• and
• an end plate disposed on said fourth side covering said fourth opening.
