which hose is the vacuum hose

[arclite20]

Does any one know which hose coming of the inake maifold is the vacuum line in a 97 Corolla. i think its one on the back.

Any hose going to the intake manifold after the throttlebody is a vacuumline.

[arclite20]

so would that be a good place to install a vacuum gauge?

just look for a free connector port on the manifold and run your hose, if theres no free ports put a tee in a line right by the manifold, so your getting a true reading
