These hoses come off the throttle body and tap into a V and were routed under the plenum but went nowhere. There's nothing after the V junction and we can't find anything hanging. I drew an orangish line over the hoses I'm talking about.
Does anyone have a clue where it's supposed to go? Thanks!
I am currently struggling with this same line. I understand that the two lines off the throttle body join into one. They are connected to a vapor purge valve solenoid and then to the charcoal canister. The solenoid has a two-line electrical connector. Finding that connector and the solenoid that fits it, is the problem I am dealing with. I found a two-line pigtail that runs with the distributor line. It was capped off but I believe it is in the right position between the throttle lines and the charcoal canister. Good luck!
I am assuming you are aware there is a vacuum routing label under the hood. It should help but if not, there others that will post with additional info.

Phone apps don't always show signatures, so you may need to switch to a real browser in desktop mode on your phone, or just use a desktop/laptop computer. Put your location in your profile & upload an avatar of the truck. The more pics you post of the truck, engine, wiring, labels, & undercarriage, the more likely we can help you. So far, all you've told us that needs to be in your signature is: 90 5.0L
We assume it's an F150 because you're posting on this BBS, and we know that the 5.0L (EFI) was derived from the older 302ci, so those are redundant.

You should post your own thread in the '87-96 forum, including more detail about what you mean. Are you saying you can't find these ON YOUR TRUCK, or that you can't find replacements to buy? Post that answer in YOUR thread - not here.

Technically, it IS a vacuum line that carries fuel vapor, but it's not connected to FULL MANIFOLD vacuum; it's connected to (ported) throttle vacuum, and it's still shown on the vacuum map on the VECI label, as Jim said. On this map, it's the dotted line (and this truck has no CANP):
