You Rebel You.....There's been some discussion about running distributor vacuum from a carb port or from the manifold. I found better results running my distributor vacuum from the manifold.
Good Luck, L.M.
Try each one. Probably the only practical way to tell the difference for us guys without sophisticated test equipment is with the good ol' seat of the pants dyno.You Rebel You.....
Still haven't made the switch myself yet, But everything I've read points to that making more sense. It's most likely good advice, though the carb guy I bought my Motorcraft from included coming off the carb.
If you have and HEI and an aftermarket Carb a 4.2 without the PCM, Everything can go except the Dist advance, the 4wd vacuum to the Cad, the vacuum for the defroster vents and the lines to the charcoal canister.
If you still have the Stock carb and PCM I wouldn't touch a thing except to make sure they are all in good condition.
I think with the CTO removed the cannister is basically useless at this point. I just never felt the urge to Remove it. Probably should have when I replaced the coolant tank a few weeks back. Nice to know it isn't necessary.I actually don’t have my canister hooked up either. I read debates on either side, and I don’t have a gas smell that some reported with it gone, so my OCD against clutter won out and I’ve kept it disconnected, getting rid of a few more lines.
