the fourth hose to the diverter valve

ad5mb · 11-16-2012, 03:01 PM

I have three large hoses going to the diverter valve, and one open vacuum fitting on the bottom. looks like a 3/16 hose goes there. where is the other end of that hose?

it turns out I have a major vacuum hose disconnection infection.

a brown plastic tube that connects to the top of the rear solenoid in the middle
a black plastic tube that connects to the bottom of both solenoids in the middle
and the bottom of the diverter valve

all disconnected
