I am looking to replace the #3 water by-pass hose in my '94 4runner. I went to AutoZone today to see if they had one in stock. The guy helping me took me in the back and I was able to narrow down their selection to 1. I bought it. My question is, does anybody know the diameter of the hose I need to replace? From my understanding this hose is a pain in th eyou know what to replace. I would prefer to know if taking off the hose will even be worth it. Thanks in advance!
