Stupid vacuum lines

[b2redneck]

Gonna start chasing down leaks and replacing vacuum lines. Which vacuum lines are the bare minimum that are necessary to have a reliable running engine?

Not concerned about emissions, no testing in my area. Smog pump and cat are already gone.

Bare minimum? IIRC just the one going to vacuum advance if they have that stock, never dealt much with the stock ignition system so I'm not sure if it does. You might want to leave the one for the brake booster in place as well.

If you have the computer, you need all of them. If you can do it legally, go with DuraSpark and then all you need is the vacuum advance hose.
