Other Fuel System Tank Assembly problems of the 2003 Mitsubishi Lancer

Upon inspection of the undercarriage in the rear, areas of severe corrosion has developed underneath the rear on the aluminum subframe bar that holds the rear differential and other suspension components in place such as the rear differential & lateral control bars that can surely compromise the cars ability to drive if unnoticed. Additionally the fuel lines along the gas tank, as well surrounding surfaces on the driver side rear, have developed noticeable corrosion as well that is also proving to be a large area of concern. I am certainly concerned for my safety when operating this and the vehicles road worthiness because of these areas. This vehicle is by no means heavily modified at all, the vehicle is never operated beyond its limitations/aggressively as it's always been great for me as is, and it resembles exactly the way it did when it left the factory. Sourcing original and dot approved replacement parts has become very difficult and it leaves me at a standstill. Please if there isn't some kind of road worthy directive in regards to this I believe there should be because it can certainly compromise safety for driver in command as well as other drivers on the roads. To whom it may concern and whomever reading this, I hope my information came off clear and is considered. I greatly appreciate you taking the time observe this and making a prominent decision. I can provide additional photos and videos upon request as well. Thank you for your time.
