I have a 2000 chevy 2500 4x4 with a 5.7 bi fuel setup. I go stuck with no phone in about 5 degree F weather with a bad fuel (gasoline) pump. I had just got the truck and the cng was filled by me but it didn't work. When I found a fuse (40 amp) missing under the hood I took my heater fuse and got the truck started but the cng tank started to leak out of the fill valve. I had no choice but to get out of were I was so as I drove the leak got less with speed and the indicator would drop. As I slowed down the leak came back. I did get home with the windows open and freezing. I understand that this was dangerous but in this situation I wasn't going to freeze to death and I was within 15 miles of home. I have no idea why the tank leaks even when the key is on and the fuse is in it leaks. Is there a pressure relief valve or something else that could cause this. The tank holds cng fine except for when you turn on the truck. By the way it is a ex dot truck fresh out of service with 141000 miles.
