I am replacing my halon bottle on my race car I had Halon 1211 in the old bottle the new one they sent has DuPont FE-36 is this compatable with my existing system or do I need another halon type, I do not want to replum the car. And is this a powder type or like the halon and will not fill the car with powder if discharged?? If so I will have to send it back and chew out the salesman (since I told what we were replacing). It is a Fire Bottle system.
