Can you help me identify these 2 hoses. They are not hooked up to anything so I want to make sure they shouldn't be.
Here is the first one it is by the brake booster

it goes down here by the air box

The 2nd hose is right by the silver ac hoses in the pic. Its a hard plastic line with a u shape that hooks up to nothing. Thanks in advance!!

 

Looks like part of cruise control, which uses a small electric vac pump near the air horn in second pix. Cruise vacuum is not connected to manifold vacuum.

The crooked plastic hoses on firewall are vent lines for things like differentials, etc. They allow oil fumes to vent away. If plugged, seals can leak from the slight pressure that builds up. Also lets condensation have a way to evaporate. Small insect like to build nests in them, mud chiggerz, etc. They terminate on a "banjo" bolt on the item being vented.

 

Ok so the first hose does not need to be hooked up to anything? And second hose is a vent hose?

 

Yes both counts.

 

Perfect thank you
