Noticed that the far left injector is leaking at the return line. Upon closer inspection, we discovered that the flare nut is split in half. I smeared a little JB Weld on it, and that changed nothing. This thing is pouring out massive amounts of fuel. Wondering if the nut is replaceable, or if the entire injector must be replaced? Best I can tell, this is the Case 336BD 4 cylinder engine.
