Brake Disc Pads problems of the 2004 Chevrolet Corvette

I own a 2004 Chevrolet Corvette. While the vehicle was parked in the garage I smelled a strong fuel odor. I checked and he replaced the gasoline cap, and noticed a gas puddle on the ground washed the vehicle but could still smell fuel. The vehicle was taken to a Chevrolet mechanic who diagnosed the failure and confirmed that the fuel tank pipe connectors were defective. The fuel tank connectors could not be replaced; therefore, the fuel tank had to be replaced. The vehicle wasn't repaired. The failure mileage was 35,400 and the current mileage was 35,400. The Chevrolet dealer diagnosed the following issues: needs left side fuel tank and sending unit $3,887. 50, rear brakes pads and rotors $517. 50, front brakes pads and rotors $482. 50, brake flush $165. 00, induction and injector services $350. 00. Service rear posi diff. $165. 00. Currently I am a cancer patient and due to medical cost I am unable to afford the repairs. This vehicle is the only mode of transportation that I have. Any assistance that you could afford me would be greatly appreciated shouldn't the issues be a recall/safety issue. Thanks in advance. . R. Thomas.
