The line is about 3 feet long on mine ( I think it uses about 6 feet of rubber hose total, I had to replace all of it becasue when I bought the car all the rubber lines were in very bad shape). I used FI clamps on all of it, 2 on each of the high pressure connections. If it only would be a problem if the regulator fails, I guess I will just change it next time I work on the car then. I figured with how long that line is it might not be a bad idea anyway. lol
