Fuel line,plastic connects to metal ?

I have a leak on the metal supply line between the gas filter and the tank. Its located on the side of the tank between the gas tank and the body. no room for patch work. do you know if the dealer sells the complete line combo of metal and plastic?, or seperate pieces? I tried to mate the same type plastic line to metal before and had one painfull time trying. is there a trick to doing it? I heated the plastic to push it in place but it seemed to not shrink back and I had to clamp it. the plastic line that is on there appears to be shrink wrapped onto the metal line. THANKS FOR ANY HELP YOU MAY HAVE.

I can not recall what that looks like.
Is it any thing like this ... Thunderbird Fuel Rail Rebuild (http://www.mn12performance.com/mn12how-to/fuel-rail/fuel-rail.html)

Thanks for the info. I did not know that slip on hose was availible. The stuff I used a while back was plastic and impossible to slip onto the metal line. That hose looks like it slips right on nice and easy. I just dropped the tank down and it only took about an hour.Now I'm off to the Ford dealer. THANKS
