Fuel Leak

[Daxman]

Today while working on my truck for other issues im having we noticed one of my fuel lines is leaking at the fitting or quick connect. Its not dumping fuel out it but seems to be a dripping every 10 seconds or so. There are 2 metal lines and its the one on top on the drivers side by the steering shaft, is there a way i can just put a new O'ring in there or do i need to buy new fuel lines.

the fitting on the pump ? sometimes you can spray the thing with brake cleen and get it to reseat,usually dirt built up.
