Compatible AN hose for turbo scavenger pump
Compatible AN hose for turbo scavenger pump My gravity drain for my single 7875 isn't cutting it so I am installing an Exa nano. Planning to run 10AN to the pump and 8an to the oil pan. I'd really like to avoid using PTFE hose and use something with a better bend radius.

I don't see why PTFE would be needed, any oil specific line should be fine.
I've used Evil Energy AN line off Amazon several times with good results.
I'd also recommend using a small reservoir off the turbo for the pump to pull from instead of the pump pulling right off the turbo.

Thanks for your thoughts. I don't really have room for a reservoir, I'm running directly from the turbo to the pump. I've read that is still OK. I hope that since I'm running the nano it will be overall less vacuum on the turbo seals.
There was a guy on YB recently who had that problem, the oil pooled in the line enough and the pump pulled air through and not oil and it caused the turbo to smoke.

Best to run as big of a line as possible. -10 line is part of the issue. AN fittings are another. Use drain fittings with 3/4 ID tubing minimum and 3/4 ID hose. No need for any AN fittings or connections on a low pressure drain setup. (even with a pump.) You likely wouldn't even need a pump if you had properly sized drains. Very common for guys to go up to 1" on a drain line.
I'd grab one of these and modify it.
It has the turbo flange, use some rubber hose to attach at the other end.

I had 3/4" copper (actual 7/8") drain but the slope was so low that under decel it would smoke. I'm going to run the same 7/8" line into the Exa nano pump. Only concern is around pulling vacuum on the turbo seals if I don't run a reservoir.

If anything, it would help pull oil through the turbo and keep it from smoking.
My last car ran a turbo drain that was -10AN iirc nearly flat from the turbo to a spot on the pan maybe an inch from the pan rail above the drain plug.
I also used a MM PCV Catch Can which I firmly believe put the crankcase under vacuum and helped pull oil from the turbo/drain because I never had a smoking issue.
Only time it ever smoked was because I was braking hard on a downhill a freeway off ramp, so the oil backed up for a few seconds, never happened again.

Verdad Gallardo I know two guys who've run these pumps (not that pump specifically), both ran the pump straight off the turbo and didn't use a vent and had no issues.
I always ran a vent on the setups I did. They all had vented sumps and the pump pulled from the sump. Tiny amounts of vacuum would be fine and may even help. If you get too much it can pull the oil mist past the "piston ring" shaft seals and into the housings and smoke.
