My F-250 7.3 has developed a fuel leak on the drivers side behind the front tire wear the hard metal line connects to the steal braided line.
do they sell new o rings for this or do I have to replace the whole Braided line.

 

I would replace the entire line... Those look to be in bad shape anyway.

 

Uh...yeah...I agree with CSIPSD. This is one time an o-ring replacement is not the best way to go. Get new lines.
