Ok stsill having problems with truck jerking back and forth until I mash the gas then the other 7 cylinders put up the slack. Not good but still trying to find the problem. I'm going to switch from autolites to motorcraft and see if that works Cause autolites sure as hell ain't. Question though looking at the motor from the front on the left side there is a black can which looks like a juice can. is that a charcoal filter? if so should both ends be hooked up meaning the hoses? one end on mine isnt. I started the truck up and it's taking air in and didnt seem to want to stall. thats what got me thnking. any help thanks./

NOPE! Just the top. It has a little two port manifold in the top. TWO HOSES!
They will rust out at the top seam if the canister is mounted UPRIGHT, like on my old '87. but on my current 93, the can is mounted on its side (go figure), and hasn't rusted out yet due to improved drainage.
Take a small screwdriver and just very easily check for bad spots on the edge of the top, push down slightly and if it moves, you got a bad one. The can was about $47. at Ford (Baltimore price). Haven't seen the plastic one gatesj is talking about, although you could make one out of schedule 40 PVC pipe and a couple of end caps. The ambulance (86 E-350 extended) I used to drive had a 4' section of 4" with end caps and fittings drilled and sealed after we wnt thru two cans in as many years. Mounted outboard of the frame and secured to the body. NEVER had anymore problems with losing vacuum at the heater controls, or for the patient suction. You could do a smaller version for a heck of a lot cheaper.
