Fueling your NGV is easier and safer than fueling with gasoline or diesel. It takes the same amount of time, but you don't get smelly stains on your shoes or spills down the side of your vehicle.

For fueling with a Sherex/OPW attachement watch this video.
Instruction for Fueling with CNG.
• The driver pulls up at a dispenser, switches the engine off and then connects the nozzle to the receptacle. Now you are ready to fill.
• Use appropiate paying method to activate dispenser.
• When the cylinder is full, the dispenser automatically shuts off and then driver disconnects nozzle. Its that simple.
CNG Cylinder Fill Amount at CNG Station
CNG cylinder manufactures supply industrial standard amounts for the cylinders they make. This amount will not be what you are able to refill the cylinders when fueling at the cng station during normal use. Amount of refill will vary at different stations and other factors will effect amount of refill like the weather, temperatures, CNG fuel station equipment, altitude, storage vessel psi, temperature compensation, etc...
The cng cylinders will always have cng fuel pressure remaining in tank when the fuel gauge shows it is empty due to CNG fuel rail pressures that are needed to supply cng fuel to the engine. For example we see for a manufactuer rated 23.5 gge cylinder having refills in range of 18 - 20 gge's. It is possible to have even lower refills. Altech-Eco does not guarantee the amount you will get on refills, there are just to many variables out of our control.
How come my fill amount of CNG changes?
If ambient temperature goes up or down, pressure also correspondingly goes up or down.
CNG is typically stored at 3,600 psi at 70ºF. During fast filling, CNG heats up as it compresses into the tanks.
Example: On a 70ºF day you fill your NGV to full at fast fill station.
You fill to 3,600 psi at an elevated temperature (say 100ºF) in the tanks.
As the CNG cools back down to ambient of 70º the pressure of gas decreases.
Your end result is less gas - instead of filling at 3,600 psi you may only have filled to 3,400 psi.
You are more likely to get a more full fill on colder days than on warmer days.
IMPORTANT SAFETY NOTICE
If the receptacle on the vehicle and the nozzle on the dispenser do not match, do NOT use an adaptor to refuel the vehicle. Industry standard nozzles and receptacles have been designed with optimal safety in mind to prevent such accidents.
