Re: 4kq diff locks....finally

[Wolff <wolff_b@ix.netcom.com>]

Green hose from drivers side accumulator runs up to a tee at the center
of engine bay near fresh air. One side goes rearward to HVAC? the other
is immediately connected to a blue one way valve. From there to another
tee located over the distributer. One side of this goes to diff locks
(rigid clear/semi opaque tubing.), the other towards intake manifold and
another tee. One side of this tee is stuck (loosely I discovered in my
case) into the isv hose that likes to collapse and the other side is a
rigid pink plastic hose that goes into the passenger side fender well.
This is on a US '86 4kq with AC.
HTH,
Wolff
