5.9L Cummins fuel line

Iíve got a 2002 bluebird all American with a 5.9L Cummins. The fuel line has come detached at the head and is spray diesel. Iím attaching an image from the video I took.
Iím guessing itís the o ring and that itís not compression fitÖbut this isnít my wheelhouse so to speak.
I need to be on the road tomorrow night, do I need a new line? How do I disconnect/reconnect? If I go to a shop what part should I even be asking for?
Please help

I can't tell which fitting is detached from the dark photo. From the fuel pump to the filter housing is a banjo bolt and washer. From the filter to the VP44 injection pump is a banjo bolt and washer. From the VP44 injection pump to each injector tube is a hardline that is compression fit with no oring. The injector tube or hardline can be replaced if needed

Thank you, that gave me enough to figure out it’s the fuel injector cylinder. I’ll call around tomorrow in hopes someone near Savannah has one.
How do I determine the line number, I think it’s 2 or 5
Is there a video where I can learn to disconnect the old broken one and reconnect the new one?
Am I going to have to drain the tank I just filled…

I looked up replacing them…it seems as easy as turning the nuts and replacing the line. It can’t be that easy

You might consider replacing the injector tube as well..
