[QUOTE=texan_idiot25;198798]The ingenius way to clean out a semi-rusty gas tank:
1st, we used garden rocks from walmart and tossed in a few handfuls in the tank, we used a teeter-totter motion (My dad and I holding the tank at each end, one going up, one going down). This was like a rock tumbler, knocking off TONS of the rust.
Step 2, take out the rocks, nothing really fancy... Putting fingers inside the sending unit hole and catchign rocks as they roll past.
Step 3, while vacuuming took a good bit of the powdered rust out, it couldn't get it all. Thus, our ghetto... HIGHTECH FILTRATION DEVICE: [QUOTE]
Wow what a sofisticated way of rocks to take out rust.
