Fuel Water Separator Filters
Filtration matters, that's why Doc's Fuel Water Separators are crafted from high-grade filter medium, providing maximum filtration and minimal flow restriction. Our filters keep your fuel system performing at its best by filtering out water and other contaminants from your fuel before it enters your engine. With regular maintenance and Fuel Water Separator Replacement, you can significantly reduce damage to your engine and avoid costly engine repairs. Fuel water separators are particularly critical in diesel engines because water in diesel fuel can cause injector damage and microbial growth, leading to sludge formation. Doc's Diesel Filters are spec'd and designed to meet or exceed the quality/performance of the original filters (OEM's) that come in your vehicle. Choose from Cummins, Powerstroke, EcoDiesel, Duramax, and more when you shop below and enjoy fitment, guaranteed.
