Anybody know what the clear hose is for? It's on the drivers side, runs from the very back maybe to some kind of vent up to under my dash somewhere and I can't find where it goes from there. Car is gutted and trying to clean it up a bit, not sure if this is something to replace or remove all together. Thank you.

 

That looks like the fluid feed to the rear window wiper.

 

wow didn't even think of that, thank you. I don't have a rear wiper any more so that didn't even cross my mind.

 

Yep, that would have been my guess as well. Trace it up to the nip at the top of the rear window. May as well remove it too, since you don't have the wiper. That's at least 1-2 ounces of hp unleashed.
