The picture below is of my vacuum line going down to the transmission. I was wondering if anyone could tell me
1. What size is the line I need to pick up?

2. What is that round thing sitting between the two lines, and do I need to find a new one?

3. Anything I need to be scared of?


Thanks for the help as always

The "round thing" is a check valve and needs to stay. Buy some new hose, cut the two pieces to the exact size and fit them onto the check valve, and your good to go!

Check valve? Mine has nothing there but hose... Am I missing something?

I don't think so. I was talking to Echo earlier, and he didn't have the check valve in his either

I have one, but I don't think it'* a check valve. I just went out and blew into mine and it'* not one. I'm not sure what it is.
