Can't say for sure, but I had to force the hard steel lines a bit to get them to line up with the openings in the bypass block. I also had to put threadseal on the lines threads because I had an oh so slight drip from one of the lines.
I also had to tighten them more than I'd have liked and struggled to get the lines back into their retaining brackets, more than I should have had to do in my opinion.
I didnt have issues like hemiman, but it was a bit challenging, more than the ats install video on the 68rfe with two of the lines that are soft and easy to manipulate. Hemi did not report any of those issues with his rev max block
Good call on the bypass you ordered. I just wasn't overall impressed with the quality of the ats block and customer service. Just my opinion
