Injection pump fuel return fitting welded shut (1 Viewer)

I was doing a once-over on my 12H-T fuel system and found that there is supposed to be a fuel return line, but there isn't one to speak of on mine.

In fact it looks like the previous owner must have put a slug of weld inside the fitting to seal it shut. That can't be good?

The engine has been running just fine, but now I'm starting to suspect if this (over-pressurization) is the reason why there is so much fuel getting into the oil.

UPDATE: It definitely was welded up. I drilled it out and fitted a new return line. Originally I thought this was a typical farm fix but it runs just fine after I reverted it. I may do an oil sample at the next service interval to see if this resolves the fuel contamination issue.

Where is the return going? Its suposed to go back to the tank.
