Fuel tank

[old guy rich]

Hi guys, happy Thanksgiving to all. I have a question about changing my sending unit on my 55 Ford Victoria. I was in my good clothes today but had the idea to pull out my sending unit, knowing there was a little cover in the trunk floor would make it easy. I took the cover off and the sending unit wire just went forward out of sight, no sending unit in sight. Do I need to pull the tank or can I just jack the car up and get to it that way. Thanks.
