Diesel drip from fuel injector hardline

[teddythetwig]

Hi all,
I recently put Argo back into the water and noticed a small drip coming from the nut on the injector hardline. It drips once every few seconds, but I'm worried that it could turn into a bigger problem. I'm guessing that it is some sort of leaky gasket or o-ring. Does anyone have any suggestions?

Sorry if I'm stating the obvious but have you tried tightening it?

Remove it, clean the surfaces well and retorque.
It’s a metal to metal seal, maybe there is a burr or tiny piece of dirt?
Flared fitting, had to remember what it’s called, double flared if memory serves.
Be careful tightening, it can crack the flare and of course the leak gets worse.

Generally they use ‘one & done’ crush copper washers..just replace and torque to engine specs.
