97.0 VT Roadster / 08 Gallardo Spyder
I’ve been in the fuel tank area a couple of times, Seth and Leslie. The sender unit on my car was working just fine and I only had 18,000 miles or so so I left it in place but I did replace the gasket. The sender unit is not a bad idea to replace at this age, however. In terms of replacing the tank, I have not heard of failures to the tank but it does look quite impossible to get out without taking the rear quarter panel off the car. All the fuel lines and high pressure hydraulic lines for the front lift are in this location as are fuel pumps and radiator tank. All of that area with the quarter panel out should be replaced as you don’t want to do it again.
