Re: 95 Crown Vic Interceptor fuel gauge stopped working.
You may need to fabricate something and\or do some welding. Not sure how the CV did it, but I've seen them bolted both sides and I've seen them bolted on one side and sort of hinged on the other with something similar to what you're showing. Hopefully someone with more CV\GM experience can weigh in with a better answer.
