280S: 1975 Mercedes 280S (M110 engine) - replaced Solex

Customer Question

1975 Mercedes 280S (M110 engine) - replaced Solex carburetor with Weber kit K248. Need help setting vacuum system back up.
The weber has two ports (advance and retard), but the stock Solex 4A1 that came with the M110 engine had seemingly more vacuum lines going in. They connect to EGR valve, air pump, exhaust return valve and vacuum booster as far as I can see. I will try to attach a diagram I drew in the next step.
Can you help me fit those connections to the simpler Weber? Also, my car is exhaust exempt in California, so if we need to bypass any of these that's probably fine too, as long as we make sure it doesn't affect the car running.
