Help identify this part and leak?

Hello:

I have been hunting craigslist for months looking for a V4 first gen tacoma. I think I finally found a 2002 at a decent price.

I went to take a look at it and snapped some photos of the undercarriage. It looks like there is some kind of leak. I'm not smart enough to know what part of the truck or what this leak could be.

What part is this? Is the leak significant?


Thanks,

Steph

 

Need a pic from the other direction to see what is sitting on the frame in that area. Put your finger in whatever is leaking, what does it smell like? Fuel, oil, etc? I am assuming something with fuel since its right by the tank?

 

Looks like water leaking out of the frame rail, probably from a drive-through car wash.
