I am doing the breather extension for the diffs and both gearboxes, I wanted to replace the lines on both the transmission and transfer case as the stock hose does not look very sturdy
I traced the transmission line up to the top by feel and found the barb felt loose, like it was mounted in rubber or something, got a mirror out and it looks like plastic? Kind of hard to tell through the road grime, I figure if it is plastic I will likely break it trying to pull the stock line off
Is this barb plastic? Is it threaded in or press fit? What can I replace it with?
