ABSTRACT:
A fuel primer pressure accumulator for an internal combustion engine fuel supply system capable of storing fuel under pressure when the internal combustion engine is stopped. The accumulator has a chamber formed by a casing and a pressure element. The accumulator is connected at a fuel inlet passage to the fuel supply line between the fuel pump and the carburetor. The accumulator is connected at a fuel outlet passage to a primer valve and through the primer valve to at least one fuel primer. A check valve is contained in the fuel inlet passage. The check valve permits the passage of fuel into the chamber when the internal combustion engine is running and restricts the passage of fuel out of the chamber when the internal combustion engine is stopped, thereby trapping fuel in the chamber.
