Aurorasters R12T Fuel/Water Separator 10-Micron Filter — 30 GPH Marine Direct-Fit, Transparent Bowl

Aurorasters R12T is a 10-micron marine fuel/water separator that delivers 30 GPH flow and removes water and particles to protect engines across boats, trucks, and industrial equipment.

Built for marine and heavy-duty use, the R12T combines a high-capacity synthetic 3-layer filter media with a transparent reusable collection bowl and an automatic exhaust to trap water and contaminants before they reach fuel pumps and injectors. The unit is corrosion-resistant, easy to install as a direct-fit replacement, and matches common part numbers used in Racor and Parker kits.

How does the R12T prevent water and debris from reaching my engine?

The R12T uses a three-layer synthetic filter that captures particles down to 10 microns while separating and collecting free water in the bowl. A rotating element and automatic exhaust assist in clearing trapped contaminants so filtered fuel leaves cleaner and drier.

• Three-layer imported synthetic filter paper for consistent particle removal
• 99% efficiency at removing 10-micron particles in high-performance flow
• Transparent nylon collection bowl lets you see water accumulation
• Automatic exhaust device helps remove excess dirt and water

Is the R12T easy to install and maintain on boats or trucks?

Yes — the R12T is designed for plug-and-play installation as a direct-fit replacement; it aligns with common ports and threads for many Racor/Parker models. Routine maintenance involves replacing the filter element and draining the bowl when water is visible.

• Direct-fit replacement for R12T, S3240, S3213, S3227, 802893t and similar
• Connecting size M18 x 1.5 center thread with NPT/ZG1/4-19 ports
• Pre-fill the filter with clean fuel before starting to avoid air locks
• Do not reuse old filter elements — always fit a new cartridge

What performance and durability features should I expect?

The R12T balances high flow (30 GPH) with strong contaminant removal and corrosion resistance, making it suitable for saltwater and heavy-use environments. The housing has an electrostatic powder coat, and the filter media is engineered to protect fuel system components like pumps and injectors.

• 30 GPH flow capacity for continuous fuel delivery
• Electrostatic powder-coated housing for corrosion resistance
• Filter protects pump nozzles, piston rings, and cylinder liners
• Reusable transparent bowl speeds visual inspections

Which engines and machines work with this separator?

The R12T is versatile and made to serve gasoline and diesel engines across marine, automotive, and industrial applications. Use it for boats, generator sets, construction gear, mining equipment, trucks, compressors, and other machinery that benefits from cleaner fuel.

• Marine gasoline and diesel engines for recreational and commercial craft
• Trucks, construction machinery, and mining equipment
• Generator sets, compressors, and industrial engines
• Petroleum and fueling equipment requiring reliable filtration

Who is this for: The Aurorasters R12T suits boat owners, fleet managers, mechanics, and equipment operators who need a reliable, high-flow primary fuel filter/water separator that fits common replacement part specifications. Choose it if you want visible water collection, robust 10-micron filtration, and a durable housing for marine or heavy-duty environments. For best results, install as a direct replacement, prime with clean fuel, run the engine briefly, and inspect for leaks.
