ABSTRACT:
A quick connect, disconnect adapter for a fuel pump outlet and a fuel line inlet in the form of a tubular flexible element with ends to slip over, respectively, a pump outlet nipple and fuel line conduit. A one-way duck-bill valve is molded integrally with the element to retain fuel in the fuel line when the pump is not operating. A coil spring embraces the element to confine the ends. A central portion of the element is expansible to absorb and modulate pump pulses and is confined against abnormal expansion by the coils of the spring. The coil can be slipped axially to release confinement of one end to allow ready removal from the pump outlet.
