Bent water tank cover

Somehow the front corner of my Galvanized water tank cover got bent. I filled the water tank and it is not leaking. I removed inspection plate and there is of foam insulation between water tank and cover. The damage is close to water tank drain valve.
The inspection cover is distorted and could allow critters to get in. I would like to remove cover because there is not much room to work to beat cover out.
Can this galvanized cover be removed without the tank dropping?
There looks to be 4 screws going through cover and up into floor on each side next to frame.

The tank pans are usually made of heavy gage galvanized steel. The tank's weight is supported along the pan in such a way as to tilt the bottom of the tank so the water runs to one end. As long as you don't cut the tank along the long axis of the box and the area you are dealing with is small, you can just cut out the damaged area of tank pan and replace it with new stuff that is attached with screws or rivets. If you are dealing with a large area, I would use 3/16 stainless steel rivets but you will need an air operated pop rivet gun to put those suckers in unless you are pumped up like Arnold. You can use Aluminum rivets as well but they won't be as strong. I did about half stainless on mine and the rest aluminum when my arms gave out with the stainless rivets. Also use short drill bits in areas below the tank so you don't drill a hole in it.

You can get small sections of galvanized steel from a hardware store or 4x8 sheets from an HVAC supply store.

So the sheet metal dose hold water tank in place? There are no straps just the sheet metal supports tank.

Yes the sheet metal supports the tank. It is not think stuff like you put on the roof of a barn. It is like .040" thick. I would remove a section on the bottom and the back edge and then make an L-shaped patch. The main thing is you don't want it touching the tank and wearing a hole in it. Otherwise it won't hurt to leave it that way assuming it is not putting stress on plumbing going to and from the tank.

My black and gray tanks were bent by someone missing the axel mounting plate and hitting the tank pan.
