The problem with doing it through the fuel pick-up is that not only can you not inspect the inside of the tank well, you can't clean it either. IMHO it is no biggie to remove the fuel pump and inspect the boot, the pick-up hose, and the baffle more completely, drain the fuel, and then put everything back. Since this is one of the "hidden" areas of the car I like to look in there once in a while. When you get a good look in there you can actually see a bubble of water floating in the fuel, shiny pieces of metal, dirt, etc in the fuel. In many cars the baffle is either not properly assembled or parts are broken or missing. You just can't tell all this through the fuel sender. David Teitelbaum vin 10757
