No. Per the rule book "All fuel tanks, lines, pumps, valves etc. must be outside of drivers compartment. and within the confines of the frame. All fuel tanks must be isolated from the drivers compartment buy a firewall.

Fuel tank has to be completely isolated from driver in case of accident.
Rule 1:5 FUEL SYSTEMS
Location: All fuel tanks, lines, pumps, valves, etc. must be outside of the driver's compartment and within the confines of the frame and /or steel body. Cool cans, fuel distrubution blocks, etc. must be located at least 6 inches forward of the flywheel/bellhousing area on rear wheel drive (RWD) vehicles, and on opposite side of flywheel/housing area on front-drive vehicles. Fuel pressure gauge isolaters, with steel braided line, may be mounted on firewall.
TANKS: When permitted by class regulations, fuel tanks located outside body and/or frame must be enclosed in a steel tube frame constructed of minimum 1 1/4-inch O.D. x .058 chromoly or .118 mild steel tubing. All fuel tanks must be isolated from the drivers compartment by a firewall, completely sealed to prevent any fuel from entering the drivers compartment. All fuel tanks must have a pressure cap and be vented outside of body. A positive-locking screw-on fuel tank cap is mandatory on all open-bodied cars. Insulated fuel tank prohibited. When used, fuel cells must have a metal box protecting the part of the fuel cell that is outside of bodylines or trunk floor, excluding hose connection area in rear. non-metallic fuel cells or tanks must be grounded to frame.

Steel plate would not be required if it's mounted between frame rails and under the floor. Most of the ones i've seen have had an access door in floor for fueling.
