Hi guys,
just got this rig, 1998 Discovery ls and when looking a the engine I found these two plastic tubes coming from deep between firewall and transmission coming out right at the spark plug wires connections..What Are these and why are not connected...and where do they connect to??? help

 

those are the vents for your diffs and transfer case

 

Excellent. I had the same question, too.

 

You can repair the broken black plastic clip on the fuel return line from the pressure regulator with a zip tie.

 

So they don't connect to anything just need to be tightened somewhere??

 

they stay open, they are vents to the atmosphere

 

Binvanna is. Saying zip tie that metal fuel line to its bracket

Leave the 2 plastic lines as they are

 

You guys are awesome. Thanks
