Wing Fuel Systems – other heavy-duty road engines: the collective page of Ford base engines converted to natural gas and LPG, 6.6 to 7.3 litres, 227 to 401 hp, model years 2018 to 2026
Wing Fuel Systems is a US converter that adapts diesel base engine platforms for heavy road vehicles to natural-gas or LPG operation and certifies the resulting engines separately with the EPA. This page gathers the engines the register could not assign to a named range; chassis designations such as E-450 or F-650/F750 and the engine-family codes with the digits 06.6, 06.8 and 07.3 point to the underlying Ford 6.6-, 6.8- and 7.3-litre engines.

The register lists here 6 versions with 227 to 401 hp rated output at 4,000 to 4,676 rpm, all with sequential fuel injection. Four versions run on compressed natural gas, two additionally offer petrol as an option. Model years range from 2018 to 2026. Maximum torque ranges from 337 to 368 Nm at 3,230 to 4,482 rpm; certification applies to the USA in each case.
Natural-gas and LPG conversions such as those from Wing Fuel Systems target fleet operators of vans and medium trucks looking to switch to alternative fuels, for instance in urban delivery traffic or municipal fleets facing emission requirements.
When buying a used vehicle with a converted gas engine, what matters above all is the condition of the gas tanks and their inspection dates, the tightness of gas lines and injection valves, the condition of the spark plugs on the petrol-capable versions, and complete documentation of the conversion and EPA certification; service and spares run through the Wing Fuel Systems network.
