Ive searched google and multiple forums to retrieve a pic & part # for Happy Hummer.
Part im attempting to find is....
hummer 2007 H3 engine crankcase ventilation hose located on bottom of resinator nearest back of engine. Autozone & Napa both no go.
I find the # to be...15123628...but no pic. Ordering blindly is no fun.
Unless one of you happened to remove the lil black hose when upgrading and could let me get it from ya.
Pls. Tank You.
