Should you hook up all of the vacuum line on a Chevy truck 305 V8?

yes but. there are two "vents" that are part of the vacuum system that have no hoses connected to them. If more information go to www.autozone.com. Then click on repair info. Make sure you have entered the vehicle year, make, model and engine. then click on drive-ability & emission's look in the long gray column on the right hand side of the screen. at the bottom you will see a link for "vacuum diagrams" there are about 15 different configurations on how the lines should be hooked up. just find your engine and it will pull up the diagram. they are hard to read though
