Systems and methods are provided for delivering, and controlling the delivery of, one or more fuel additives to one or more fuel hoses at a fuel dispenser. The system comprises a plurality of additive storage tanks, each containing a fuel additive, and a plurality of additive lines for delivering a different fuel additives to the fuel dispenser; a pump coupled for drawing a corresponding additive into and pressurizing the additive line, and a pressure transducer coupled for measuring a pressure generated within the additive line. The plurality of additive lines terminate into one or more output manifolds arranged at the fuel dispenser, wherein each output manifold comprises a plurality of solenoid valves, each coupled to a different additive line. An additive delivery controller is included within the system and coupled to each pump, pressure transducer and solenoid for controlling the delivery of the fuel additives to the fuel hoses.

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.

Embodiments of a heating system maintains the temperature of a fuel additive (e.g., AUS32) at and/or above freezing temperature to avoid crystallization. The heating system can form a fluid circuit with one or more coaxially arranged sleeves disposed about hoses that transport the additives. The fluid circuit can also include a central compartment that encloses a flow meter. A fluid heater couples with the fluid circuit to provide heating fluid, e.g., to the central compartment. The heating fluid disperses throughout the heating compartment and into the sleeves, thereby direction heating fluid in thermal proximity to the hoses and other components that handle the fuel additive.

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.
