Was it the box that caused the issue? Saw that there was fluid sprayed around when the hood was up plus the trail it left. The pump quieted down once you had more back in and the air was bled out. Sounded fine after you took it back out.
We're still trying to figure out what the cause of the problem was. The box may be bad. I didn't go out on the track after that and on the drive home the hose kept popping off due to too much pressure in the return line. I eventually had to flatbed home.
I hope you can find a definitive root cause. I think a lot of folks here would like to know what happened.
