Got one. installed and troubleshot it myself
Make sure it isnt getting air in the system.
90* elbow was my weak point.
The one that came with the system fit sloppy so I ended up going to ACE hardware and getting another and it fit a little tighter.
I still had a super slow leak at that 90* elbow on the piston cylinder that is on the firewall, that even though it says not to, (and I called Keisler to say that I was thinking of doing it, and they said "what-eva") I used teflon tape.... I did and it fixed the issue.
might be something to check.
