Does it matter whitch hole in the abs pump the front line and rear line go in to? I can't find anything on line that is real clear. I replaced both front lines to the wheels im on th master to pump but i didnt pay attention when i pulled them out. Any hel would be appreciated.

 

Yes it matters. Unfortunately I am not around my Hummer today to take a picture for you.

 

From what little info i have found on this it looks like the front line of master goes to the driver side top ob abs pump? I think.
