A point-of-sale fuel dispensing system, a pump assembly and a method of dispensing fuel at a point-of-sale. The system includes a market fuel storage tank, pump assembly, fuel conduit, separation unit, numerous enriched fuel product tanks and a controller. The separation unit may selectively receive at least a portion of market fuel and convert it into an octane-rich fuel component and a cetane-rich fuel component that may be subsequently dispensed to a vehicle being fueled, where a fuel grade selection and retail payment of a fuel containing the octane-rich or cetane-rich fuel components is provided to the vehicle based on user input at the customer interface.

A fuel hose for delivering multiple-grades of fuel is provided and in one embodiment includes a first hose portion having a first length and a first diameter, and a second hose portion having a second length and a second diameter. The first hose portion includes a first fuel line and a second fuel line, and the second hose portion includes a third fuel line. The first fuel line and the second fuel line can be fluidly connected to the third fuel line. In one embodiment, the first diameter of the first hose portion is larger than the second diameter of the second hose portion. The invention further relates to a fuel dispensing unit.

Kits of parts for assembling a hose connection, fuel dispensing units having such a hose connection, and methods for assembling such a hose connection are provided. In one embodiment, a kit of parts is provided that includes a plurality of hose connection parts selectable from, first hose connection parts including one fluid inlet and one fluid outlet, second hose connection parts including two fluid inlets and one fluid outlet, and third hose connection parts including three fluid inlets and one fluid outlet, which kit of parts is suitable for assembly of a hose connection having at least a first and second fluid inlet and a fluid outlet, according to any one of three configurations.

Fuel hoses are provided herein to deliver a blend of fuels. For example, a fuel hose is provided that includes an upper hose portion with a first channel for delivering a first fuel and a second channel for delivering a second fuel. A lower hose portion with a third channel extending therethrough couples to a nozzle. The lower hose can couple to the upper hose portion at a joint that receives the first and second fuels. The first and second fuels can mix at the joint to form a blended fuel that is delivered through the lower hose portion to the nozzle.

The disclosure relates to methods for distributing alcohol-containing gasoline. The methods herein facilitate the combination of gasoline blendstocks and alcohols to create finished gasoline products. The methods herein also measure the volumes and other characteristics of the gasoline blendstocks and alcohols and employ computers and controllers that calculate the gross and net volumes of liquids, including the net volume of finished gasoline products.
