Peterbilt 2015 cm2350 list of issues

[tree98]

It's a pump that makes as much as 30k psi. There are numerous places the system could be leaking internally and you'll never know unless you do the leakdown test. It takes about 5 minutes with insite.

If you have someone else runs the test, make sure to find out exactly how many psi it loses and in how many seconds/minutes. Don't come back here and say "yea it passed" and not have the specifics lol :)
