Great kit But One Issue

I installed the Fleece CP3 conversion kit on my 2011 Duramax and overall, the installation went as expected. The kit is well designed and the components appear to be high quality and fit well.
The only major issue I encountered was with the supplied low pressure fuel line. I was extremely careful during installation to ensure the fitting was properly seated and torqued according to specifications. Before completing the installation, I pressure tested the line and discovered the fitting was leaking. I wasn’t sure it would stop but after an extreme amount of tightening the leak finally stopped.
Fortunately, I caught the issue during pressure testing. If you want to save yourself many hours of taking things apart again, I highly recommend pressure testing the fuel line before complete reassembly and seriously consider reusing the factory low pressure fuel line rather than the supplied replacement. If I were doing the installation again, I definitely would reuse the factory line. Aside from this issue the kit performed as expected and the overall fit and finish were good. Fleece needs to seriously look at this issue as I see others have had the same problem.
