What is this part?

Hey guys im getting trouble code 41 and it seems to only happen during city driving conditions, so i was thinking it mite be fuel supply related. i was bored at work so i climbed under my truck and found gas leaking from this mystery part. its on the driverside frame and looks like it has 2 selenoids on the bottom of it... i cant figure it out but its leaking and i thought maybe thats the cause of my code. this is a pic of the part. thanks everyone.

FIX IT ASAP!!!!!!!!!

that's an abs module of some sort, and fluid leaking from it means you aren't going to have brakes soon!
