What are the line that run behind the battery for? I didn't want to remove the battery to find out. I notice there is also a line that goes through the firewall on the driver and pass side. Any Ideas?
Thanks

Rubber line is wiper washer hose
Plastic lines are vac for heater controls and boost guage.

 

there is a box that mounts on the backside of the Batt. tray that has some vac. lines going to it.

 

TX thats the box/lines I'm talking about. Now I know what the fire wall lines are but the others???

The ones that go behind the battery go to a small vacuum tank that helps the emissions stuff. If you remove the battery tray the vacuum tank will come with it cuz it hangs on the back of the battery tray.

Thanks!!

 

It's a vacuum reservoir for running the A/C with the truck off (controls the mix door)

I took it out, under boost i now go from dash vents to defrost..lol
