    Cleaning fuel tank

    Long time no see. Havent been here in a long time. My S4 has been sitting in my driveway for YEARS but I'm finally trying to get it running again. Shouldn't need that much work. First order of business is the fuel pump....

    Somehow, everything in my fuel tank got really badly corroded. Maybe it was from an additive I used too much of, or maybe bad fuel? Idk but the plastic hose that the pump delivers fuel through got cracked, and the jackets are flaking off of all the wiring in the tank and the wires are all really badly corroded. I will add a Pic of the pump I just pulled out if I can, not seeing the option so far...

    I have another pump I can use, but i want to clean out the tank first and apparently I will also need to replace both fuel sending units, unless I can just replace the wiring which I might try. My main question for the forums right now is, how to clean out the fuel tank?
