[Blue Tank]

After I saw a few threads about the return lines being a possible cause I looked them over better. The ones from the oil cooler looked a little wet so I added a worm clamp to the worst one and it seemed to be a little better. The cooler had some decent rust on it so I ordered a new one and the one from the hydro to rez. Changed them last night and it's about the same thing. If I still had hair i'd pull it out. At this point I could have created a second problem from running the system with the original problem. I'm going to change the p/s pump next.
One question I have is about opening the rez. Every time I open it you get the sound of pressure or vac escaping. Does this say anything to you guys?
