'71 Power Brake Booster Check Valve (and thermal sensor)
So, I have had a look this morning
The big hose goes to the intake manifold
The small one goes to the carb base.
I don't know why two vacuum lines are required (or maybe because I have a Midland dual-diaphragm booster?).
Unfortunately, I don't have the 1971 service manual, but in 1970, there is only one hose on the brake booster check valve :
Hiltopautoparts seems to sell the correct dual-port check valve, but it's NOS.... and the price :BangHead:
