Fuel Leak

I just put the IP back in and I have new leak that i cant figure out how to fix. Ok see if you can follow me on this as I cant upload picture. On the back of the injector pump are 8 fuel lines. 4 for the left bank and 4 for the right bank. They go back and curve down to connect to the top of the injector. Then they are held down by 5/16 inch nut or what ever you call it. When i tighten that down it leaks out of the bottom of that nut. Anyone have any idea how i can stop that from leaking? I have herd mention of 00 orings but i was under the impression that was for the seats of the fuel injectors.

Do you mean 5/8" nut? Where the injector line attaches to the injector? Injector lines are known to crack there. Id take it apart and inspect.

I had to replace the injector to solve the problem but I think it's the line that's bad. I just can't find the line at the moment.

Thanks again for the help again
