There is a hose attached to the right side fender that goes down to the engine support frame into a device that I dunno what the hell it does. The hose has a plug and its about 1/4 inside diameter. Does anybody know what it is for?

 

Picture? Probably a vacuum line or a windshield washer fluid line, or fuel or vapor line for the evap system. Who knows without a picture of the line or the "device".

 

Will snap one tomorrow, it's too dark now. Definitely not washer fluid as I just replaced my wiper motor and it is located on the other side of the engine bay.

 

You may want to supply truck info also.

 

This would help.....

 

Sounds like diff vent.

 

It's a 1997 1500 with the 5.2L engine 4x4 5 speed manual.

 

Pic of the hose in question?

 

There's the pics. Hopefully somebody will know what that's for. I'm new to trucks so there's lots to learn.

 

What pics?
