Freightliner ‘pass-thru’ manifold

Thats exactly what I did. Worked well....just have to have a little patience with the O-ring. Little finesse saves a lotta dough lol

This should be done with caution though.. some of those air-lines in that block are not simply pass-thru ... but feed multiple circuits. Not all of them can simply be drilled out...

This was my back up plan in the event I couldn't repair the fitting. Anything beats changing out that (what looks to be ) pain in the a$$ manifold if not absolutely necessary.
