Fuel tank and general purpose engine equipped with the same

A fuel tank having an upper portion with a fuel inlet in the center of the top, and a lower portion, both of which are virtually square, made of a resin material, and connected with a flange, comprising:

• a depression surrounding said fuel inlet on said upper portion, of which the cross section is a trapezoid, and which slopes downward toward one side of the fuel tank and opens onto an end;
• a groove on either side of the depression and oriented along a same direction as said depression, which opens onto said same side as said depression;
• and
• a gutter provided along an entire periphery of said tank, which is formed between said ribbed flange and the periphery of said upper portion, and segmented by a plurality of ribs to form a segment of said gutter on at least one side of said periphery, said gutter segment being provided with an opening extending to an exterior;
• wherein said two portions of said tank are welded at a web of a ribbed flange which extends along an entire periphery between said two portions.

A general purpose engine wherein a fuel tank is provided on top of said engine, said fuel tank having an upper portion which has a fuel inlet on the top and a lower portion mounted to said engine, both of said upper and lower portion being joined together with a flange, a recoil starter being placed at an end of a crankshaft, said general purpose engine comprising;

• a depression surrounding said fuel inlet on said upper portion which slopes downward toward a recoil starter;
• a gutter provided around periphery of said flange;
• and
• an opening in said gutter to allow spilled fuel to discharge from said gutter onto a recoil starter side where said recoil starter is located;
• wherein said gutter provided on said recoil starter side, is segmented by a plurality of ribs to create a segment of said gutter and said opening is provided in said gutter segment.

A fuel tank having an upper portion with a fuel inlet on the top, and a lower portion, both of which are connected with a flange, comprising:

• a depression surrounding said fuel inlet on said upper portion which slopes downward toward one side of said fuel tank;
• a gutter provided around periphery of said flange;
• and
• an opening in said gutter to allow spilled fuel to discharge from said gutter to an exterior;
• wherein said flange comprises a ribbed flange running along the entire periphery between said upper and lower portions of said fuel tank which are welded at a web of said ribbed flange.
