I have a 1979 F-150 Ford Pickup truck with a 400 engine and automatic
tranny. Something got under my hood and tore up some vac hoses.
(Probably a raccoon). Replacing the hoses themselves is not the
problem. Knowing where they go is......
There is a TEE with 3 or 4 hoses directly behind the carburetor near
the firewall. One is plugged, one goes to the tranny via a metal
tube, the other one is completely missing so I have no clue what goes
there. I think I have the others figured out, but would like to know
for sure. Can anyone furnish a scan or link to a website with this
By the way, why wont the tranny shift into 3rd when that hose is off
for the (vacuum diaghram or whatever thats called). I had no 3rd gear
till I put that hose back on.
