What size and how long of a hose do I need to replace the PCV hose? Also with what little I could see back there it looks like there is a junction off the hose that comes off the valve? The valve doesnt seem to be able to be replaced. On a second note, the water doesnt make it to the rear. It seems to pour out behind the body of the Tahoe right before the driver door. Anyone know how I can fix that?

if you feel up behind the splash guard in the drivers wheel well, you will feel the plastic or nylon line that runs to the back, most likely cracked. Fill you tank a bit and hit the squirter. Feel around the leak area and pull pull the leaky line down. Probably the tire contacted the well and cracked it. I used an air line quick connector for air brakes to fix mine. Cut a small piece off, go get the connector, and slide your lines in each end. less the cracked stuff. Then tuck it back up behind the splash guard/ wheel well
Originally it was an issue that the line came loose there. I could see the water pouring out and all. I have since fixed that issue and it worked for a day or so and developed a new one. As of right now it still doesnt work but no visible water when the button is pushed. The line works all the way back to the rear fender where there is another connector.
So it's squirting some where in the rear quarter but no leakage? I know my wiper/washer wont go on once and a while due to a message of rear access open, rear glass microswitch needs adjustment. Once I push on the glass its all good. I believe it was a 5/16 OD coupler that I used, so 5/16 line I guess
