Re: Power brake push rod adjustment

In the finishing stages, Here is a pic. The canister is behind the booster and the pump is in the forefront. The pressure valve and relay are behind the pump. I just have to finish the electrical and hook up the vacuum lines. But I'm wondering about the tee connection to the original vacuum line from the carb. I can't find a 3/8" check valve any where. I was thinking of "teeing" in for redendancy (back-up) if the pump fails. At least that way, I'll still have 11-13 inches of Hg.
So, if I "Tee" straight into the old line, will that affect the current vacuum to the engine? The only check valve that I can find is a small Dorman (#47149 1/4" x 1/8"). If I install that, I will have to "Gerry rig" the conections( No big deal. Last question, which way should I set the one way valve?
