A fuel fill system for use on a tractor having a lower fuel tank provided with an upwardly projecting fuel fill neck and an upper tank connected to the lower tank for flow communication therewith is disclosed wherein a filler tube is sealed against the fuel fill neck to define the inlet opening for the introduction of fuel into the lower tank. The filler tube is provided with a distal elbow defining an outlet opening positioned below the upper tank to direct gaseous bubbles within the fuel away from the filler tube to collect in said fuel fill neck or in other remote parts of the upper and lower tanks. A vent hole is provided in the filler tube near the inlet opening to allow the fuel to rise within the fuel fill neck as the upper tank fills. An adapter is threaded onto the fuel fill neck to capture a flange formed on the filler tube at the inlet opening to seal the filler tube against the fuel fill neck. A detachable cap is threadably received on the adapter to close off the inlet opening.

[ Having thus described the invention, what is claimed is:] [1.] In a tractor having a wheeled chassis adapted for movement over the ground; an engine supported on said chassis to provide operational power therefor; a fuel tank apparatus for holding a supply of fuel for said engine, said fuel tank apparatus including a first tank portion having an inlet opening and a second tank portion in flow communication with said first tank portion, said second tank portion defining a cavity separated from said first tank portion by a barrier such that said cavity is closed off from said first tank portion when the fuel level within said fuel tank apparatus reaches said barrier, said fuel tank apparatus further including a fuel fill neck connected to said first tank portion in flow communication therewith for the introduction of fuel from an external source of fuel through said inlet opening into said fuel tank apparatus, the improvement comprising:a filler tube positioned within said fuel fill neck and terminating internally within said fuel tank apparatus, said filler tube having a smaller diameter than said fuel fill neck and being sealed against the inlet opening of said fuel fill neck such that the introduction of fuel into said fuel tank apparatus must pass through said filler tube, said filler tube being operable to direct gaseous bubbles within said fuel into said first tank portion to collect within said fuel tank apparatus outside of said filler tube, said filler tube being provided with a flange at said inlet opening, said tractor further comprising an adapter releasably connected to said fuel fill neck to sealingly compress said flange between said adapter and said fuel fill neck.
