Re the Vacuum Tank
First check that the suck line is working to the vacuum tank. Disconnect it from the tank and blow through it to make sure ts clean, then listen for bubbles in the tank. The tank has a top feed so if there's a leak or the pipe has broken off in the tank its not gonna work. Its pretty easy to take the suction pipe out of the tank to check it too. If that's all ok you may have to dig into the tank. That's a little more complex. If the little valves are free they probably work so..1. Check the float no leaks. 2. lift out the inner tank and check the checkvalve at the bottom. 3. Make sure the vent hole isn't plugged. 4. The top must be sealed - make a new gasket. If you need any more direction post a reply or pm me.
And Yes, the little plug on top is so you can put some gas in the tank to prime the system,.
