A safety relief system for a CNG fuel supply of a vehicle includes first and second Type 4 cylindrical tanks, each having a shutoff valve at a first end and an outlet at a second end of the tanks. First and second relief devices are attached directly to the shutoff valve of the first and second tanks, respectively. Two separate relief outlet lines are connected to the outlets of the tanks. A common relief line is located generally parallel to and lying between the first and second tanks. The two separate relief lines are both connected to the common relief line. Third and fourth relief devices are connected to the common relief line. Each of the relief devices is constructed to relieve pressure on both the first and second tanks in response to either an excessive pressure or and excessive temperature at that relief device.
