Water in fuel tanks. It’s a common issue that can mean trouble. Water can freeze in the lines, damaging them or making your fuel kind of gel-like. Even in warmer climates, unwanted water in fuel can cause rust or unwanted growth of organisms.
Water is heavier than fuel, which means it will accumulate at the bottom of your tank. So how do you get rid of it? The PIG Water Hog was developed specifically to sink to the bottom of your tank and suck up all that water
This unique absorbent only absorbs water, not fuel. It has a polymer inside a small nylon sack which is encased in a plastic housing. It comes with an easy-to-use retrieval line that can be attached to your tank or the underside of the fuel tank cap, to keep the absorbent from falling into the tank. This is especially important if your tank is in a moving vehicle.
The Water Hog works best with fuels. It often comes up whether the product will filter water out of oil. Oils can be tricky because they can coat the nylon bag containing the polymer, which makes it difficult for the water in the oil to get through to the absorbent.
Another one we hear a lot is “How do I know when the absorbent needs to be changed?” That’s an easy one. When the water is absorbed into the polymer and the bag expands up against the casing of the product, it needs to be changed. The units are meant for one-time use and cannot be dried out and used again.
Check the water hogs periodically to make sure they don’t need to be changed and that they are still attached to the tank.
