leaking injector?

[arthr31]

so tonight, on the way home, i could smell oil. first thought it was a blocked crankcase breather (only 8*F out), but that was OK. Then i noticed that one of the lines going into the injection pump is leaking.. This is the line that goes into the front of the pump (first position). There's a slight pool around the base. I don't think this is normal since no other inputs have this pool. i tightend the links around it, still the same. ..

What's to do about this? Is this a real problem? i get a quarter size drip ever 24 hrs?... should I start looking for new injectors or what ?

I suppose this'll worsen over time, so i should take care in feb when i'm having other work done... thanks for the input.

i can post a pic if helpful but not tonight, too cold
