CNG/RNG and Diesel
The process for refueling a natural gas vehicle is almost identical to the process used at local gasoline stations. Most dispensers accept credit cards, and the filling time is similar to using a gasoline pump. Most stations have no attendants on duty, for which you’ll need to follow the instructions provided.
Instructions to operate most public CNG dispensers:
- Turn off your engine. Do not smoke.
- Remove the vehicle’s dust cap and take the fueling nozzle off its holder.
- Align the arrows on the nozzle so they point to each other.
- Place the nozzle over the fuel receptacle and push it on.
- Rotate the lever so that the arrows point away from each other to lock the nozzle on.
- Insert your fleet or credit card and follow the instructions on the screen.
- Once payment is authorized, lift the dispenser handle, and fueling will begin.
- When the fill is complete, lower the handle to turn the dispenser off.
- To disconnect the nozzle, slowly rotate the nozzle handle 180 degrees until the arrows are again pointing to each other.
- Remove the nozzle. You may hear a slight release of pressure.
- Return the nozzle to its holder and replace the dust cap.
