I'm running copper line from the manifold on my 216 to a fuel pump w/ vacuum assist then back over to the wiper motor. What size line should I be using? 1/8 or 1/4?

Also, if I'm going to eventually add a brake booster, can I "T" the line after the assist pump and run both the wipers and the brakes safely?
...what about also adding a vacuum defrost fan to the mix?

Thanks!
