Your chevy (and mine) do not have a changeable fuel filter. The filter is housed inside the fuel pump module inside the gas tank. You have to replace the entire pump if you want to change the filter.

After being in 3 feet of water, you may have a number of problems. If you have water in the engine, you may want to start by removing the spark plugs and turning the engine by putting a socket and half inch ratchet on the crankshaft bolt and turning manually to remove any water in the cylinders. Drain the oil and change the filter so you remove any water in the oil pan and add fresh oil. Turn the key to see if it cranks. If it doesn't crank, check the status of the battery. If all are done and it still doesn't crank, you may have problems with the vehicle's computer and may require further diagnostics to determine the problem. I hope this helps you. Good luck.
