my truck is a 1998 (pre 1/14/98) f-150 4.2L V6.. aluminum intake plenum..

my new engine is installed, and alllmost ready to go.. everythings done except 3 little hoses.. i'll start with the one that seems to be the biggest problem.. theres a metal y-pipe that comes out of the water pump.. its sealed with an o-ring.. the 2 larger hoses are plugged in, (if i remember correctly theyre for the heater core) but theres a tiny little metal tube that comes out of the top-most hose.. right under the throttle body, curves about 90-degrees upward.. and its about.. 1/4".. or 1/3" in thickness.. i'm stumped.. i dont know what plugs into it...

now for the other 2.. one is a plastic hose about 1/2" thick.. it's plastic, it has a slight curve about half way through, and a 90 curve on the end, with a rubber grommet.. its coming from the PCV.. and i dont know where the other end goes.. aaand the other hose is about the same thickness.. its all rubber.. with a metal clamp on the end.. it's coming off the back of the intake... theyr both about a 1-1/2ft long.. and located on the passenger side (left side looking at engine).. if i have to i might try to start the truck with them plugged.. but i'm thinking they could affect the IMRC actuators.. because they run on vacuum.. i really want to get it right.. i spent all this money on this truck its all ready but this is whats been holding me up...

thanks for reading any help is appreciated..

Major apologies for not repsonding sooner. I have been out of touch a bit here lately.

Did you ever get the hoses hooked up?
If not, I'll grab the haynes manual and see if I can help.

Again, sorry for the delay in responding.
