A fuel dispensing unit for refueling vehicles, comprising:

• a base module containing dispensing hydraulics,
• an electronics module for controlling said fuel dispensing unit and having a user interface,
• a nozzle module for holding at least one nozzle for dispensing fuel from a fuel reservoir by means of said dispensing hydraulics, said nozzle module arranged horizontally to a side of said electronics module,
• a column module, and
• a top module,
• wherein said electronics module is arranged vertically above said base module, said nozzle module is arranged vertically above said base module, said column module is arranged vertically above said nozzle module, and said top module is arranged vertically above said column module such that said column module elevates and supports said top module,
• wherein the nozzle module includes a vertical mating connection for vertically mating to the base module and the column module, and
• wherein the vertical mating connection comprises protrusions formed on the nozzle module and projecting in a substantially vertical direction, and wherein the base module and the column module include corresponding recesses for receiving said protrusions.
