I just did all hoses, the rear heater has 4 hoses under the passenger seat area. Moderately tight spaces with engine and transmission out. I used 1/2" gates hose from NAPAwhat exact hose does this special heater hose replace?
also, if i wanted to replace all the hoses at the firewall which plumb in the rear heater, it looks like all those short pieces aren't available separately. is the recommendation to get some bulk hose and cut them to length and piece it together? if so, what diameter hose....1/2" gates green stripe? i have a bypass kit but do enjoy the rear heater and am conflicted on whether to fight w/ all those small hoses at the firewall or just give in and bypass it all like i did the PHH and a long length of 5/8" green stripe.
