I will probably need to clean my fuel tank, have read some threads and suggestions.

Someone said to see if the tank needs to be cleaned by taking off the fuel sender guage from the top and shining a light in there. So I started thinking, rather than taking the entire fuel tank out to have it cleaned, why not just clean it with a pressure washer from that area? Leave the fuel tank on the car. Run the car low on fuel, drain the remaining fuel, take off the fuel strainer at the bottom of the tank, hook up some kind of a funnel for the sludge to come out into a 5 gallon bucket, put a pressure washer wand inside the fuel sender area, blast it clean, then let it air dry in the nice hot sun for a few hours, and close it all back up?
