changed valve cover gaskets yesterday. and while i was hosing down the engine bay. i was wondering what some of these things were??

i noticed a line that goes into carb had a little hole in it on the bottom side. never touched it before so i didnt notice. but that was one of the first things i touched. and when i touched it, i felt water, or so i thought. pulled it off carb and noticed it was swollen and gas was leaking thru.

i traced the line and it went into a round canester looking thing on driver side. below the lights. dont know what it is.

so i looked around and took a couple pics of things i was unsure about.
obviously im no mechanic. and lack much knowledge.

thanks for any help.

Someone else can correct me if I'm wrong:

1. Charcoal canister for fuel.

2. Appears to be part of your cruise control, if you have it?

3. Looks like your wiper motor.

4. ???

charcoal canister.. whats it do?
truck has cruise. dont think it works tho.
both things in 3 are wiper motor? my wipers work. but the spray function does not work. not sure if its cuz the arm in my truck that controls the wipers i broke or if its the motor. not sure where the motor is to replace tho.
thanks for reply.

that thing in picture three is your wiper motor... and the round ball is part of the vacuum for your cruise control.. the charcoal cannister takes fumes from the gas tank and vents em o ut for you

I believe #4 is your air pump, for the exhaust emissions

your squirter pump for your wippers is mounted to the backside of the wiper fluid resivor and if the switch is broke thats a good reson it dosnt work but the pump probly has corroded and dosnt work ether

The vacuum reservoir also holds vacuum for your HVAC controls. You want to keep it.
