Holy feakin sig batman! You have the biggest sig I have ever seen.

The o-ring washer could be bad at the back of the head. Also the T fitting isnt that close to the banjo on the head. You should be able to see if its coming from the T or the head. Do you have fuel driping or is the truck just hard to start?
 
it is not hard to start at all and it drips fuel only when it is running the tee fitting seems to be dry so it must be the banjo bolt what are the chances of the line cracking

You check the o-rings on the banjo bolt?

Also look at the #6 Injector line as well.
 
Have you looked at the little rubber connectors on the return line? Just a piece of hose over a flared fitting but will pop off with enough twisting of the drive train.
 
i replaced the o-ring washers on the banjo bolt and it is still leaking fuel when running what else could it be
 
Check #5 or 6 crosstube. With the motor off spray brake cleaner or either on 5 and 6. blow of with air real good. And start it and let it run. Sometimes they will leak with it running or when shut off. Check #6 with a long handle mirror and light.
 
i found the problem it was 6 tube i couldnt see it leaking so i swap it with number 4 and it leaks real slow thanks you all for your help
