My jag is a 1984 not 1990. I have Dual gas tanks, can't get my car to start.

What is your question?

one tank has too much gas in it. I keep filling the other up. is it a pressure valve malfunction? I found a canister on the right passenger side that has nothing in it and has a bottom plate that is falling off. it has a hose at the top that isn't attached to anything.
