What is this?
I rolled under my truck tonight to check the air in the spare. I thought I knew most everything about my truck. Above the spare there appears to be some type of plastic box maybe 5" high about 18" long and 7''wide. Has (1) 2 wire connection, and several small hoses and 1 large soft hose coming out of it. They go to the frame rail and I can't follow them very well cause the fuel tank is there. Will be interesting to know what this does. Thank you... Spotty...

It should be connected to the fuel tank and filler neck as well as running up into the engine compartment and connecting to the rest of the emissions control system. If Im not mistaken that is your charcoal canister...it basically allows for the movement of vapors from so that they arent released. Kinda like the expansion tank in your cooling system.

Thanks everyone, nice pic NcRanchero, that's it exactly! Man, I can't believe how rusty my truck seems underneath, that's Minnesota winters I guess, still no rust on the outside though.
