Can I use a 3,000 psi rated cylinder on a 3,600 psi system?
No, filling a 3,000 psi cylinder to 3,600 psi will put excessive stresses on the cylinder and will cause it to fail. However a 3,600 cylinder can be used on a 3,000 system, providing that the vehicle is only refueled from a 3,000 psi dispenser.
If I run out of fuel (CNG) can I siphon natural gas from one vehicle to another?
No, the vehicle will need to be either refueled at a fuel station or refueled from a cascade.
If I run out of fuel (CNG) and tow the vehicle at a fuel station will I need to “bleed” the fuel system after it is refueled?
No, the high pressure system will recharge with fuel as soon as the ignition switch is turned on. The fuel pressure regulator should allow fuel to pass thru to the injection system without the need to bleed.
I have found a CNG cylinder that is 3 years past the “Do not use after” date, can I use this on my vehicle?
No, this cylinder must be correctly and safely made ready for disposal.
What is the difference between Dedicated, Bi-fuel and Dual-fuel vehicles?
- Dedicated; gasoline system has been removed and a CNG fuel system installed
- Bi-fuel; vehicle has a gasoline and CNG fuel systems. Generally the vehicle will start on gasoline and will switch over to natural gas when optimum operating conditions are reached
- Dual-fuel; vehicle has a diesel and CNG fuel system. Generally the vehicle will start on diesel and will start to introduce natural gas during certain drive conditions. Engine runs on a mixture of diesel and natural gas
