FUEL TANK FOR AN OFF-ROAD VEHICLE A fuel tank construction having a non-vented filler neck and cap, a shut-off valve sealed to the tank by a fluorocarbon bushing, resistant to both alcohol and sunlight, is positioned in the tank such that, upon bushing failure, no more than ten percent of a full fuel tank would leak therefrom, at least one protruberance having an air pocket formed therein and a vent system connected to the protruberance communicating between the air pocket and the atmosphere. The venting system consists of a long plastic tube attached to the vent and routed over the upper surface of the tank having the open end positioned such that any fuel which might discharge through the open end is directed away from the tank and any vehicle it might be attached to. Additionally, a low fuel sensor may also be incorporated and connected to the tank by a similar bushing as that used to connect the shut-off valve. The low fuel sensor utilizes a casing having pin holes surrounding a thermistor. This sensor arrangement reduces the sensitivity of the sensor to sloshing fuel. The shut-off valve and the low fuel sensor are connected to the tank such that no more than ten percent of a full tank is at or above the two bushing connections. |
