1997 Chevy Suburban

Hello, you need to get all the lines loose first, gas lines, electrical connections, the fill hose, whatever. Drain the tank.

Doing it by myself on some makes and models, I have used a floor jack, I did use a 1 foot by one foot piece of plywood on the contact point.

A couple of guys might be able to handle it, I'm not sure how heavy and awkward your tank might be.
