02 f150 with the 4.2 engine i have zero idea what these are for?? 1st is by the brake booster some container and flying saucer plate lol? and then it goes around the engine at the back and connects to the intake and theres another container i have no idea the function of these and than some other vaccum hose looking thing that goes behind my battery?? theres a little air box thing by the battery which i have no clue what thats for?
One circle looks like the purge valve and the clutch master cylinder, one looks like the heater hoses, and one looks like you have the starter relay circled, but maybe i'm looking at it wrong, or your circles are too big, and the pictures needs to be closer. Sorry not much help.
thanks for the reply my truck is automatic this pic is just one i found off the google and i think this ones manual. above the booster tho im not sure what that vacuum solenoid is or what that even does. the little resevour with fluid i dont have that on my truck so its N/A. and the 2nd circle in the middle has some more vaccuum hoses on the intake but im not sure what they do they are below the heater hoses. and the 3rd one on the left there is a vaccum hose that goes around past where i circled right near the battery. its some black box that holds air or who knows. no clue why theres all these dumb little things an air box by the battery?? why?? never had a vehicle with these kind of annoying tedious parts so im trying to figure out what all they do

that box is the vacuum reservoir for the HVAC system
this is off topic but i recently did my brakes and there is a little bit of air in the line or master cylinder would this cause the brake pedal to make an air spraying sound once its pressed because i can hear air or suction when i press the pedal or is my brake booster bad? i dont lose a drop of brake fluid and i cant remember if my brake pedal made this air sound before i touched the brakes
