i have a lowered s-10 that i just c-notched the frame. There was a Black box attached to the frame that i had to remove. It is attached to the fuel sending unit. Can anyone tell me what this is, can I remove it and leave it off, or should i relocate it?? If I should relocate it, do you have any suggestions as to where? Thanks,

 

Are you refering to the charcol canister? Approximatly 8wx12lx4d?

 

Yep sounds like the charcoal canister. I'd relocate it unless you like seein that ses light.
