ZXTQWX 496 Fuel Tank Filter Assembly 30‑Micron Water‑Separating Clear Bowl 25 GPM, 1" NPT

The ZXTQWX 496 fuel tank filter assembly is a water-separating, 30-micron in-line fuel filter designed to protect engines by removing water, rust, sand and debris from gasoline, diesel and biodiesel blends up to B20.

This compact, serviceable filter assembly combines a zinc die-cast top cap, a clear hyaline bowl for visual inspection and a replaceable 30-micron element engineered for high flow up to 25 GPM. Built for trucks, generators, agricultural equipment and marine craft, the ZXTQWX 496 helps prevent contaminants from reaching pumps and injectors while offering a simple installation and maintenance routine.

How does the filter remove water and particles from my fuel?

The assembly uses a 30-micron media element paired with a gravity-assisted bowl and a drain valve to capture solids and separate water. Larger particles and rust are trapped by the element while water collects in the clear bowl for periodic drainage.

• 30 micron filtration removes rust, sand and sediment before fuel delivery
• Transparent hyaline bowl shows water level and sediment buildup for timely service
• Bottom drain valve enables controlled water removal without disassembly

What fuels and flow rates does this filter support?

The ZXTQWX 496 is compatible with common fuels including diesel, unleaded gasoline, fuel oil and blends containing up to 20% biodiesel (B20) and most related additives. It’s designed for applications needing high flow, with a maximum recommended flow of 25 GPM and a typical gravity flow near 5 GPM at a 24-inch head.

• Works with diesel, gasoline, fuel oil and B20 biodiesel blends
• Maximum recommended flow rate: 25 GPM for pressurized systems
• Gravity flow example: approximately 5 GPM at 24-inch head

How is the ZXTQWX 496 installed and serviced?

Installation is straightforward: mount the filter top cap to the tank valve on the side marked “IN,” and connect the outlet hose to the port marked “OUT.” Replace the element and bowl following the manufacturer’s guidance, lubricating the gaskets with oil and hand-tightening only to avoid seizing the bowl.

• Attach top cap to tank valve at the inlet labeled “IN”
• Connect hose/nozzle to outlet labeled “OUT” and check fittings for leaks
• Coat gaskets with oil and hand-tighten bowl to ease future removal
• Use bottom drain valve to remove accumulated water before replacing element

What materials and fittings are used in the filter assembly?

The top cap is zinc die-cast and includes 1" NPT pipe fittings for both inlet and outlet, offering corrosion resistance and durable connection points. The clear hyaline bowl lets you monitor contaminant accumulation visually, while the replaceable filter element provides the specified 30-micron filtration performance.

• Zinc die-cast top cap with 1" NPT inlet/outlet fittings for secure plumbing
• Transparent hyaline bowl for easy inspection and drainage
• Replaceable 30-micron element engineered for solid and water separation

Who this product is for: the ZXTQWX 496 suits vehicle owners, fleet managers, marine operators and equipment technicians who need reliable pre-filtration to protect fuel systems from water and particulate contamination. It’s a practical option for anyone running diesel, gasoline or biodiesel blends who wants simple visual monitoring, a serviceable design and high-flow capability for pumps, transfer systems and gravity-feed setups.
