It is the line/pipe that leads to secondary consumers (coming from the forward side of the twin resonance switchover valves using line #56) that I'm trying to trace. I want to be sure the line is connected and working properly but don't want to dismantle it to find out where it goes.
Can anyone tell me if the line/pipe from the VCV using line #50 and terminating in the diagram to hose #5 (second from the right) is supposed to go to Ventilation as well as the one next to it using hose #95?
I know the line to the key stop is connected correctly.
Side note: it was actually a piece of the fuel filter bushing that had torn and was causing the leak. I swapped out the O-rings anyway (put them aside for an emergency) and replaced the fuel filter right behind the dealer. Drove 30 miles back to work and will head home to replace the pre-filter now. It was dry as A BONE!

You've got your crossover off, etc; give them and the flaps all a good cleaning. They get gummed up on your 606.910 and can cause surging problems and lack of power. Bio99 works well if you've got time to soak it as does brake cleaner on the heavy stuff.

Yes, I had planned to take the flaps, crossover and intake manifold to an engine overhaul shop in a few weeks but speaking with Roy this morning I decided to replace the fuel lines and do the manifold this weekend. Purchased all the correct parts with expert help....makes me feel like I slept at a Holiday Inn Express last night.
Thanks Terry and thanks again Roy!
