New 2007 Leak - Freezing Temps Cracked a Line

I have a 2007 Tundra SR5 Limited. Does anybody know what the lines are that sit on top of the driver side frame just behind the back side of the front tire? I can visibly see the crack just by looking in and the liquid seems to be coming from that spot. My first guess is transmission cooler line and the liquid being ATF, but I haven't been able to find it on a parts diagram yet. I'd love to not have to get it on stands in the freezing cold just to diagnose if one of you knows what that line is. There is a second one behind it that runs in parallel that doesn't seem to have any cracks/leaks.

Anybody have a Christmas miracle for me?

 

fuel line?

 

Fuel or vapor recovery. Post pics

 

Here are a couple of pictures of the line. Would fuel not ignite if I torched it? I had a small puddle on the concrete of my driveway before I got cardboard under it. I hit it with a torch so it wouldn't soak through into the ground, but it didn't burn. It also doesn't have a gasoline odor to it, but maybe that's because its so cold outside that it isn't vaporizing? I appreciate your thoughts!

 

Try to get a color on this fluid with a paper towel or something. It will give us/you more to go off

Also, don't light your truck on fire

 

If it was fuel you would smell it, paper towel method above should give you a better answer

 

Power steering?

 

...after taking a look at my truck, it does appear to be fuel related. Probably the return line.?

Does the engine run OK? Should start puking when run for a few seconds.

 

Gas over fill drain line?



O.S.T.

 

if its not a high pressure line and rubber, just get a brass double barbed fitting with some hose clamps as a temp fix until the weather warms up.

 

Thank you all for your replies! I have a paper towel under it collecting fluid now. I'll report back later this evening with more pictures.

 

I managed to trace the line using my cheap Amazon Depstech scope camera. The line runs to this module on the top of the intake manifold, which is in turn attached to the manifold after the throttle body. I circled the module in red and highlighted the line in yellow. I'm not getting any new fluids on the paper towel I placed there, but I also haven't run the truck since I parked it.

Given what the line is attached to it seems like this probably was fuel and maybe my sense of smell is just messed up? The engine was running just fine the last time I had it out, but maybe the crack isn't severe enough to create a big enough pressure drop to cause issues.

 

I think it is the fuel return line (back to the tank), so the truck should really run fine (even with the leak), and will only leak when you run the engine.

 

I found the sensor/actuator this thing is attached to. I just can't interpret the diagrams to know what part number is the attached hose. I've read the pinned guide in this forum on how to research part numbers, but I can't figure out the hose for the life of me.
