2009 Fuel Tank Removal

I have a 2009 Sonata and the tank is leaking somewhere on the top or side where I can't see it. Looks like I am going to have to drop the tank to investigate further. Anyone ever removed a tank on this model?? Looking for some guidance. I have already replaced the fuel pump on this car due to rot in the pressure line coming out of the old pump. I also replaced the plastic line and fittings that connect the pump to the tank. No leakage from those areas. I suspect maybe a seam leak on the tank somewhere. Have removed all the fuel from the tank and am getting ready to drop it for inspection. Looking for someone who has done one in the past who can guide me. Thanks
