Water In Fuel (WIF) is problematic because it can cause

Water in fuel causes corrosion, microbial growth, and fuel system damage. Water doesn’t burn, so it separates from fuel and tends to settle at the bottom of tanks and along fuel lines. That standing water creates electrolytic conditions that accelerate rust and corrosion on metal components like tanks, pumps, and lines, especially where protective coatings or seals are compromised. In diesel and some ethanol-containing fuels, water supports microbial growth—the so-called diesel bug or other microorganisms—that form slimy biofilms and sludge. These microbes, along with the acids and byproducts they produce, further corrode surfaces, degrade additives, and clog filters and small passageways in the fuel system. The combined effects—corrosion, fouling from microbial growth, and damage to pumps, injectors, and seals—lead to reliability problems and potential engine damage. Water in fuel clearly harms operation rather than improving it or having no effect.
