Aurorasters R12t Fuel/Water Separator 10-Micron Filter — Transparent Bowl, 30 GPH Flow

The Aurorasters R12t Fuel Water Separator is a 10-micron inline filter that removes water and particles to protect engines and fuel systems.

Designed for marine, automotive, and industrial use, the R12t combines a high-capacity 10-micron filter element with a transparent collection bowl and an automatic exhaust feature. This unit is intended as a direct-fit replacement for many common models (including Racor/Parker equivalents) and supports a 30 GPH flow rate while delivering reliable contamination control to keep fuel clean before it reaches pumps and injectors.

How does the R12t keep fuel free of water and debris?

The R12t uses a three-layer synthetic filter media rated to capture particles down to 10 microns while the bowl collects separated water. Its internal design encourages coalescing of water droplets, allowing them to settle away from the fuel stream for manual or automatic removal.

• 99% efficiency at removing particles ≥10 microns
• Three-layer imported synthetic fiber filter paper for durable capture
• Transparent nylon bowl for visual water and sediment inspection
• Automatic exhaust mechanism to purge excess contaminants

Will it fit my engine or equipment?

The R12t is built as a plug-and-play, direct-fit replacement for many R12T-style units and compatible Racor/Parker part numbers like S3240, S3213, S3227 and 802893T. It uses an NPT/ZG1/4-19 port with M18 x 1.5 center thread for common installations.

• Direct-fit replacement for many marine and industrial filter housings
• Port/connecting size: NPT, ZG1/4-19 with M18 x 1.5 center thread
• Suitable for gasoline and diesel applications across vehicles and equipment
• Pre-fill clean fuel on the dirty side during installation for easy priming

How simple is maintenance and replacement?

Maintenance is straightforward: remove the rotating housing for filter change and inspect the transparent bowl. The R12t is designed for easier replacement of the element and advises using a new filter each service interval to avoid contamination risks from reused media.

• Rotating filter design for faster element changes
• Do not reuse old filters — always replace with a new cartridge
• Prime and run the engine briefly after installation, then check for leaks
• Durable powder-coated housing resists corrosion for longer life

What types of equipment can benefit from this separator?

The Aurorasters R12t is versatile, made to protect fuel systems across vessels, trucks, generators, construction gear and industrial machinery. It reduces wear on pumps, injectors and engine components by keeping contaminants out of the combustion system.

• Marine engines, yachts, and small commercial boats
• Trucks, cars, and off-road construction vehicles
• Generators, compressors, mining and petroleum equipment
• Industrial machinery with inline fuel filtration needs

Who this is for: The R12t is for mechanics, fleet managers, boat owners and equipment operators who need reliable fuel cleanliness and water separation without complicated installation. If you require a durable, 10-micron replacement that fits common R12T/Racor configurations and supports up to 30 GPH, the Aurorasters R12t is designed to deliver straightforward protection and easier serviceability.
