Default horrible fuel leak

Ok guys i have an old 6.2 out of an 82 van. I drove to work today everything was fine til i put it in park and sat at an idle. It started idling pretty rough. On my way in i noticed i had a puddle under my truck so i opened the hood to find out it is leaking from the metal fuel line in between the line and nut it was not a slight leak it was squirting out fuel all over everything and was running horribly. Could my injector be bad? I havent had any time to work on it. Any ideas would help. It wasnt leaking before this thats why im wondering if my injector has failed. Please help. Thanks

Need a picture to decipher what line you are talking about?
Injector line?
injector return line?
IP feed line?

It is the metal line that runs from injection pump to the injector. Im guessing injector line. Its not a return line and it comes from the injection pump not feeds to it. But like i said its spraying out like a geyser in between the line and the fitting. Almost as if i forgot to tighten it but again it wasnt leakin before

Better loosen it off and tighten it again-otherwise you might need a new line and/or injector?

Could be that you damaged it or it has debris in the sealing area?
Or it just isn't tight yet?

Could just be a fatigue in the metal line?
Or it wasn't tight enough to start with?

You sure it's the high pressure line leaking and not a rubber return line?

Im sure...the high pressure line goes thru the fitting that fastens to the injector...its dumpin out in between the line and the fitting....its not the return lines

Ok then the injector and/or the line are damaged and need replaced.

Injectors should be replaced as a set.
