I have a 1999 F250 5.4 LD. I just replaced the PCV valve hose from back of intake. Now I don't remember how it attaches to the "Y" and if this yellow vacuum hose is connected to the "Y". Please look at my pics and explain. Thank you very much.

 

More pics of PCV valve hose. Where and how does this go?

 

Here's another pic. For some reason it's not allowing me to load multiple pics for one post. But anyways, I have a hard plastic line coming from the back of the intake. Then I have a hose coming from the side of the throttle body. It's attached to the throttle body between two coolant lines. Then I have the yellow vacuum hose line that's opposite side (drivers). Then of course the PCV valve which has a "Y" in the line. Thank you.

 

I can't help on the PCV hoses question. However, that yellow vac hardline with the right-angle rubber fitting on it could be figured out by looking at the vac diagram under the hood, if it is still there.
Ford tends to use certain hardline colors for certain vac functions. Like Green for EGR control, Red for fuel pressure, Yellow for control of fuel vapor management.
My 1997 4.6L has a yellow hardline like that going to the fuel Vapor Management Valve (VMV) that on mine is mounted on the top of the firewall on the driver's side.

The underhood sticker on mine also shows vac routing to the PCV valve, though it is just a rubber hose on mine, no tee's Y's or anything like that in it.

 

If I'm a ddick for saying this then so be it. Let me start off first by saying thanks for taking the time to respond to me. As you might have seen I'm a "Supporter" of this website. I've posted several times. So needless to say I've looked under my hood before this issue. So too tell me about the vacuum diagram under my hood is almost an insult. OF COURSE I LOOKED AT THE DIAGRAM UNDER MY HOOD! That's the very first thing I did! That's bush league! That's elementary! Jeez Louise!

 

Does the white tube in the first pic go to the purge canister solenoid above the brake booster?

 

Sorry.
From this point forward, to the best of my memory abilities (which sometimes are none too good!) I will avoid posting on any threads that you have created.
If nothing else, my comment(s) have popped your thread back up on the stack, where it is more likely to be seen by others who may be able to help.

 

I finally found a pic online. It wasn't referring to what my problem was but it showed where it went. It attaches to the underside of the vapor management valve VMV. It reintroduces spent fuel vapors back into the engine. (I believe that's what it does). My problem has been solved. But what a PITA to find out information. These F250 LD (Light Duty) are in fact a rare breed. I love my truck. However, sometimes it can be difficult to find out information about it. After all it was only made for two years. But it's all good now. Thanks for all the replies.

 

Can anyone please tell me the part # or name of the 90 degree elbow below the in plugged part in question(in the 1st picture)? Mine has melted and throws a code. I don't know the part and what to search for?

 

I’m looking for the same info myself

 

Y'all are looking for this assy. This is the complete line from the PVC to the back of the intake and the throttle body of all the parts.
