[Old Henry]

A very simple and easy way to know exactly the condition of the inside of your gas tank is to open your trunk, lift up the mat on the floor of the trunk, remove the piece of the floor that covers the gas gauge sending unit, remove the sending unit and look into the gas tank with a flashlight. You will be able to see clearly if the bottom is covered with rust and debris that would plug your fuel line and filters. If it looks clean, then it is clean and you needn't worry about that. If it needs cleaning you will be able to see it. Unfortunately, if it needs cleaned it can't be done just by draining the gas out of the tank either by syphoning or by removing the drain plug. (I tried that and it didn't work.) The tank would need to be removed to clean it thoroughly. It sounds like you've already done that so it should still be clean. Peek in and see if it is.
