Size brake lines coming from proportioning valve.

[73desertstorm]

Greetings all,

I snapped off the dang brake line going from the proportioning valve to the brake hose on the passenger side. I don’t want to buy a $95 entire kit. The fitting going into the proportioning valve is bigger than the fitting going into the brake hose. Can I just run to the parts store and replace the line?
Thank y’all,
What size goes into proportioning valve?
What size goes into the brake hose?

Some of those OEM lines had a special larger size fitting. If that's the case, make the line with a double flare tool. Remove the fitting from the old line and install on the new.
