Shit, I just ordered the USP line, should I return and get ECS? I got the Spulen block.
If you can I would say yes return it for 2 reasons.
1.) I have one that I'll send you for cheap if you want to take a chance with it. Might have been me. Yeah I just installed a clutch but we all have those dumb moments.
2.) ECS seems like a safer option as I didn't find any instances of people having issues with them. I don't remember reading anything about people having issues with the USP one either but here we are.
I could get one side in but the other side would not fit. I could get the same side into the bleeder block securely and if I flipped the line I could get it into the swirl valve securely. I tried removing the swirl valve and going directly into the master. Tried moving the O ring as it was in a different spot on one side of the USP line. Didn't help. Maybe you gotta man handle it but after dealing with the clutch install I just chucked it in the F-it bucket and moved on.
