How do you remove red dye from diesel?

Removing red dye from diesel fuel is illegal if it's done to avoid taxes or use off-road diesel for on-road purposes. Red dye is added to off-road diesel to distinguish it from taxed on-road diesel, and tampering can lead to heavy fines and legal consequences.

If you're working with contaminated equipment or storage tanks and need to clean them legally, flushing with fresh diesel and replacing filters may help—but never attempt to "clean" fuel for on-road use.
