In a General Discussion with Most Reputed CNG Fitment Center, S.K. Motors Located at Dabri, Delhi, It is found that Cylinder Manufactured by HSPCL (Sahuwala) are quality compromised. Running with CNG Vehicle with Sahuwala CNG Cylinder is deadly and can cause danger and mishappening with you & your loved ones. New Certified Cylinders of HSPCL (Sahuwala) are found to be leaking CNG Gas at CNG Pump. This is therefore I would like to request to uninstall your cylinder immediately from your CNG Car if fitted HSPCL Cylinder. And do not install CNG Kit with Sahuwala Cylinder anymore for safety reason
