Dual vacuum manifold?? By dazza (Read 585 times)

Im putting in new vacuum lines soon and noticed my spare intake manifold has dual vacuum, my standard one has only one.

Is this suppose eliminate this splitter in the vacuum hoses at all?? If so, is it better to use the dual vacuum manifold?

Cheers.

It doesn't matter, you could cap one of the nipples on the dual and split the line off of the other with a T, or attach to both nipples, or split the lines coming off of both nipples. Vacuum supplies are not like the air intake in that vac lines do not transfer molecules from one point to another. They simply provide a low pressure environment to open valves or move the diaphragm in a pump. Splitting a line several times with a T just provides the further distribution of the vacuum environment. Since no molecules have to travel through the lines molecular flow is not a consideration and they can be split many times. Having said that, I use both nipples on a manifold if they're there. It makes for one less T fitting. Rich
