Hydraulic Leak

[Smokey160]

New to this, so please excuse my ignorance. I have a 1992 B2150D that has a hydraulic leak that seems to come from the round connector with the three bolts.
I think it connects to the hydraulic gearbox.
I attached a couple of pictures of the blue line that leads to it. My question is there an O ring inside of it that possibly has worn and needs replacing?
Once I start it up, it starts dripping.

Yes there is an o-ring there. You may just need to tighten the bolts up??

Thanks for the reply. Well, I did take them out and found out that it is part of a whole piece that extends back to the auxiliary block. So, I put them back and tightened them.
where is the o ring located?

I see that there is some o-ring or gasket between the pipe and the pump (marked in red)

There are also some seals at the rear banjo bolt. See item 100 for front and 110 for the rear.

Thank you, sir! That makes sense. From Hat I could see, it appears that I will have to take the auxiliary block off since when I unbolted it the first time it didn’t come down far enough for
Me to see the o ring. Thank you again! I really appreciate your expertise.

Hi Russell, do you know if there is possibly a gasket that is supposed to go on this? I changed the o rings and noticed there’s a four screw hole but the piece only has three bolts and the fourth screw hole is covered by the piece. There wasn’t a gasket but I thinking there’s something that needs to go there because after I tighten the bolts and start the unit it is still leaking from there.
