Brake line tubing size

Anyone know what size diameter the lines are between the MC and prop valve? I was going to stop after work and get some bulk line but forgot to measure it before I left the house today. After some google searches it looks like 3/16" and 1/4" but I wanted to get a second opinion. Thanks

It's just a Jeep, and if you don't wheel it once in a while, it's not even that.

No kidding. You're a wealth of useless information.

A good parts house like NAPA will tell you the sizes and the fitting sizes you need. BTW; Yes to .250" and .187" dia lines.
Because of your SA remark to me, you can just go ahead and find the fitting sizes somewhere else, as I'm done here.
Carry on,

I didn't ask for fitting size. And who started the SA remarks? You were done before you started.

3/16" and 1/4" from prop valve to m\c. All the rest are 3/16". If you have the old fitting most stores will let you match them up. The sizes are posted somewhere just search. I used the poly line from advance auto easy to use. Good luck.
