Goldenrod Water-Block Fuel Filter & Water Separator - 3/4" NPT Top, See-Through Bowl

The Goldenrod 496-3/4 is a heavy-duty fuel/water separator that removes water and particles from gasoline and diesel while letting you visually monitor contamination through a clear bowl.

Engineered for commercial and demanding light-duty use, this Goldenrod water-block filter pairs water-absorbing polymer technology with fine micro-filtration to protect fuel systems from moisture and debris. Its zinc die-cast top cap with 3/4" NPT fittings provides a secure professional connection, and the transparent collection bowl makes inspection simple so maintenance can be scheduled before damage occurs.

How does this filter remove water from fuel?

The unit uses a water-block element made from polymers that attract and trap free water present in gasoline or diesel. As the polymer loads with water it restricts fuel flow, signaling that the element needs replacement without requiring electronic sensors.

• Water-absorbing polymer element captures free water droplets
• Automatic flow restriction indicates saturation
• Works with both gasoline and diesel fuel

Will it protect my injectors and pumps from particles?

Yes — the filter includes micro-filtration designed to stop microscopic contaminants down to about 17 microns. That helps reduce wear on injectors, pumps, and other fuel-system parts by keeping rust, sand, dirt, and lint out of the fuel stream.

• 17-micron particle capture rating for fine debris
• Reduces abrasive wear on fuel-system components
• Suitable for engines that require robust particulate protection

How durable and easy is installation?

The top cap is zinc die-cast for strength and corrosion resistance and comes with standard 3/4" NPT pipe fittings for straightforward professional installation. The construction stands up to harsh operating environments and repeated service intervals.

• Zinc die-cast top cap for rugged reliability
• Standard 3/4" NPT fittings for common plumbing compatibility
• Designed for long service life in commercial settings

How do I know when to service or replace the element?

The clear, see-through bowl provides direct visual feedback on caught water and sediment, making it quick to assess contamination levels. When the water-block element becomes saturated, fuel flow restriction serves as an additional, automatic indicator that replacement is necessary.

• Transparent bowl shows collected water and debris at a glance
• Flow restriction from saturated polymer signals service need
• Simple visual checks reduce maintenance guesswork

Who is this for: The Goldenrod 496-3/4 is aimed at fleet operators, commercial vehicle technicians, marine operators, and anyone running high-flow fuel systems who needs dependable water separation and particle filtration. It fits applications requiring up to 25 GPM flow and works where a durable, serviceable filter with visible contamination monitoring is preferred.
