Greetings! I recently purchased a bi-fuel suburban and am looking forward to sharing information on CNG vehicles. I purchased the vehicle without ANY previous knowledge of CGN vehicles. I needed a BIG vehicle and bi-fuel seems like an such an added bonus. Unfortunately, the local Clean Energy station has higher pressure pumps but there is one a few towns away that has the lower pressure. My system is made by ANGI. I hope it works out for me.
