on that valve....
those are on the left hand drive jeep cherokees, grand cherokees, and wranglers. they get brittle with age and break when you try and move the hose around a bit to do anything on that side of the engine. i think that is why its hard to find the rhd hoses, since it doesn't seem to be used on the rhd jeeps. i was going to comment on that valve and possibly using the lhd hoses last night but i forgot while i was searching before bed.
reading through more forum posts, it seems everyone has gone to the silicon lines, or used pieced together lines clamped to bits of copper pipe
