little can?
What is the little can looking thing on the right fender area of my truck, I saw someone talking about one the other day and I can't find the post on it.
What I am actually looking for is a TINY vac. hose that is the size of electrical wiring that goes to the lever on top of the heater motor and hits a Y to the can thing. lol I know I can't remember the names to anything today. If someone can decipher what I am saying and can help I would appreciate it.
It is making me feel like the woman that goes to the parts store and is asked the make and model and says RED. LOL
just fyi 80 inline 6 1/2 ton f150 with a 4 speed( actually 3 w/od)

I can think of 3 cans on the RH (pass) side...
1) A silver, pinkie-finger-sized one with one wire coming out, it's a radio noise suppression condensor.
2) A square can (frequently has the above-mentioned small can on it) is the voltage regulator.
3) Some trucks will have a Hi-C fruit juice can on the pass wheel cover, this is a vacuum reservoir.

Engine vacuum goes to it through a check valve and a tee. The check valve keeps the vacuum from being lost when the throttle is nailed. The tee takes vacuum through a tiny plastic tube into the cab to run the HVAC system via a grommet in the heater box.

Some trucks have two vacuum reservoirs on the passenger inner fender.
My 1985 F150 Lariat has a black plastic round ball that is used for a vacuum storage canister for the climate controls. This "death star" has a vacuum hose that connects to a round vacuum tee that then connects to the three-port plastic vacuum tree on the firewall.
The other is larger and is shaped like a coffee can. It is made of metal and has a single vacuum hose with a check valve inline that routes directly to the metal vacuum tree that is screwed into the back of the intake manifold. I think this one is used for the cruise control.

I knew of the Death Star ball for the HVAC system, the fruit-juice can I assume was for the engine-control solenoids.

My '86 has only the "death star" vacuum ball - no fruit juice can anywhere. And my truck does have functioning cruise control.
To the original poster (Trashyvixxen), the thin-diameter vacuum line/hose you are looking for is probably made out of a hard plastic-like material. If so, this kind of vacuum line is sold at some general auto stores (like Autozone, etc.) in relatively short lengths. Show an employee at the store (preferably an older guy or gal) what you need and they can probably direct you to it, as well as other vacuum fittings such as the little "Y" piece you mentioned.
The vacuum line can also be replaced with rubber (EPDM) vacuum line from the auto store, probably 3/16" inner diameter which they should have on big spools.
How or why do you know you need to replace this vacuum line? Is is cracked or accidentally cut?

It is in two pieces ..lol I am slowly going over her, I just got her a couple of weeks ago and spent most the time re-doing the brakes so now I am doing other stuff but she runs pretty well so far, a little rich but I don't want to touch the carburetor just yet LOL I need to driver her while in the process of fixing stuff.
FWIW, trucks without factory A/C or cruise, don't have either of these vac res.
I always thought the ball was for A/C, and the can was for cruise. I pulled one of each from an 85 Bronco that had both A/C and cruise.

I have no idea, I have wondered that myself.

They are thicker-walled than I would have thought. I cut one in half at the junk yard and was impressed with the wall thickness and general toughness of the plastic line. The one I cut was one coming from the vacuum solenoids on a 1985 I-6. But maybe some of the others are thinner/weaker.

Look on your Vacuum Hose Routing Table under the hood. The reservoir is either VRESR or VRESER, there are various other vacuum amplifiers, solenoids, valves & check valves all connected together that sometimes have vacuum, other times not.
