Over the weekend, I read several threads on the L-jet hose connections; then went and looked at mine. Map a map so I could verify the connections. I have a couple of basis questions now:

1. The throttle body has two small hoses; one goes to each side of the distributer-retard and advance vacs.
Question: Does it matter which goes to the advance and retard ?

2. AAR valve was tested and it closes when 12 volts is applied.
Question: How far should it open ? Looked about 25% open to me; and a second one does the same.

3. The decel valve has 2 large hose connections and one small one. the small one hooks up in a Y to the Fuel pressure regulato, ant hen hookk to a second Y to the ERG and then to the plenum.
Question: Is this correct ?

4. Are the boots , between the AFM and throttle body replaceable with any after market products?
