I cannot figure out how to hook up the line for the power brake booster on my straight six 250. it has the two barrel carb and I did try to plumb the line into a plugged hole at the very base of the carb in the intake but the truck wouldn't even start that way. It didn't have power brakes when I bought it and that is why I am having trouble hooking it up. Any help or pics of where it goes would be greatly appreciated.

Thanks,

Norris

there should be a threaded hole in the intake itself, at least thats where mine was on my 69 chevy van w/a 6 popper.& some have some sort of small one way check valve in the vacuum line going to the M/S..joe

Bob, Do you mean the grommet for the pcv valve because I do have it spliced into that line right now but that doesn't seem to be working. Also toomany, I did have it hooked into that spot in the intake below the carb and the truck would not start up when i routed it that way. I may try it again though we are getting dumped on right now so I will have to wait till tomorrow night or the next day that we actually get some sun. Thanks for the help guys.

does it have that di-a-fram in it???

yes it has the valve in the line. I think it is just a filter though. By the way the booster itself came out of an 86.
