fuel tank on my truck is leaking again and i need to replace the sending unit as well, its a 93 chevy 4x4 with 350 efi. whats the best way to get the fuel lines off without breaking them they are rusted up pretty bad, i had one broker loose but couldnt get the other. i even soaked them in pb blaster for a week, went out and hosed em down about every day and still had a sticky one. i wont be able to read these till this friday going out of town so hopefully there will be some replies /forums/images/graemlins/grin.gif thanks chris
 
Only suggestion I have is to make sure and use a tubing wrench (or box end if you can get it over the fuel line) and try tapping the wrench with a hammer while you hold the other wrench. The shock is what will break it free...brute force will too, but that will just twist the fittings up.
