A tension actuated fuel (e.g. gasoline) delivery hose uncoupler is disclosed in which, upon a predetermined tension or pressure load being applied to the delivery pump hose, the coupling will automatically uncouple thus releasing one end of the hose which, for example, may remain inserted in the fuel tank of a vehicle driving away from the fuel dispensing pump, and the other portion of the hose which is permanently affixed to the pump. The coupler includes normally closed checkvalves which, upon uncoupling of the coupler, close thereby preventing spillage of fuel. Further, the coupler is adjustable so that it may be calibrated to uncouple at predetermined tension loads.

In a fuel dispensing system including a fuel storage tank, a fuel dispensing station stationarily mounted on a foundation, a fuel supply line between said tank and said dispensing station, and a pump for delivering fuel via said fuel supply line from said tank to said dispensing station, the latter including a line therewithin connected to said fuel supply line and a flexible dispensing line having a free end and having a selectively operable nozzle on its free end for controlling the delivery of fuel into the fuel tank of a vehicle, wherein the improvement comprises: a tension actuated uncoupler installed in said flexible line for permitting the flow of fuel therethrough when coupled and for uncoupling at least a portion of said flexible line from another portion thereof in the event a tension load above a predetermined limit is applied to said flexible line thereby to minimize damage to said dispensing station, said uncoupler comprising a female fitting secured to one of said flexible line portions and a male fitting secured to the other portion of said flexible line, means carried by one of said fittings engageable with the other of said fittings when said male and female fittings are coupled together with the male fitting received within the female fitting for positively securing said fittings together in sealed, coupled relation and, upon the application of said tension load above said predetermined limit being applied to said flexible line, for shearing thereby to permit the uncoupling of said fittings from one another and to break said flexible line and to minimize damage to said dispensing station.
