If you have the foam on all 4 sides removed and you can move it around freely. I removed the fuel sending unit, on mine it was toward the rear and applied presure upward. It was tough but it came up thru the opening. I had a engine hoist with a chain and put a 4" bolt sideways in the tank. My tank was bad so i took it to a fab. shop and let them make me a new one from the old temp. paid $350 for a 60 gall... Than i used wedges to secure the tank in the hole. No more foam. The metal thickness on the tanks from wellcraft are not good, careful you dont go thru alot of work and than have to pull it later, they can make you a new tank thicker mill. and than your set. good luck
