Put 2 bottles of fluid through it when I changed all 4 corner brake lines and the prop valve, but ill do it again and try it out.

I did a boost leak test a couple days ago and found my j pipe gasket was toast, fixed that up, but nothing from the booster.

Could extra air be getting sucked from the booster if its ripped?

Would be unregistered and leaning me out... My plugs looked good tho.
