Parker Racor Marine Fuel Filter Water Separator 230RMAM

The Parker Racor 230RMAM Marine Fuel Filter Water Separator is a compact diesel fuel filtration assembly designed for compatible marine propulsion engines and diesel generator applications. It combines water separation, particulate filtration, and a built-in mechanical hand primer pump to help simplify fuel-system priming and air purging after service.

This complete assembly is supplied with a 10-micron Aquabloc spin-on filter element and a solid metal collection bowl designed for enclosed marine engine-room installations.

Key Features

• Parker Racor marine diesel fuel filter and water separator assembly.
• Part number: 230RMAM.
• Designed for compatible diesel marine fuel systems.
• Built-in mechanical hand primer pump in the filter head.
• Supplied with R20TUL 10-micron Aquabloc filter element.
• Maximum flow reference: 30 GPH / 114 LPH.
• Maximum operating pressure reference: 30 PSI / 206.8 kPa.
• Port configuration: 1 inlet / 2 outlet ports.
• Port thread reference: 1/4 in.-18 NPTF.
• Solid epoxy powder-coated aluminum bowl.
• Metal bowl design supports use in enclosed marine engine compartments where approved.
• UL-listed and USCG-accepted application reference for compatible diesel installations.
• Serviceable spin-on element design.

Fuel System Compatibility

Common application context includes compatible diesel fuel systems used on:

• Marine diesel propulsion engines.
• Marine diesel generator sets.
• Compact inboard diesel installations.
• Auxiliary diesel power systems.
• Enclosed boat engine compartments requiring approved metal-bowl diesel fuel filtration equipment.
• Fuel systems requiring a 30 GPH Racor marine filter assembly with primer pump.

Use this assembly only where the fuel type, flow requirement, port size, mounting space, bowl approval, and service access match the engine and vessel installation.

Fitment Notice

Confirm compatibility by engine model, fuel type, required flow rate, fuel hose size, port adapter requirement, mounting clearance, service access, and whether the system requires primary or secondary filtration. This assembly is intended for diesel fuel systems. Do not use it for gasoline unless the manufacturer’s fuel-system approval and vessel installation requirements specifically allow it.

The 230RMAM is a complete filter/water separator assembly. During routine service, the head and metal bowl are retained, and the spin-on filter element is replaced.

Replacement Filter Element Options

Compatible service elements may include:

• R20S 2-micron element for fine secondary filtration where specified.
• R20TUL / R20T 10-micron element, common factory baseline balance of flow and filtration.
• R20PUL / R20P 30-micron element for primary pre-filter / water separator service where specified.

Always select the micron rating based on the engine manufacturer’s fuel-system requirements and whether the filter is being used as a primary or secondary filter.

When This Product Needs Replacement or Service

Service the filter element when the engine reaches its scheduled maintenance interval, when restriction increases, when water or debris is present, or when the engine shows signs of fuel starvation such as hard starting, power loss, surging, rough running, or stalling.

Replace the complete assembly if the filter head, primer pump, ports, bowl, drain, sealing surfaces, or mounting structure are cracked, corroded, leaking, damaged, or unable to seal properly.

Installation Notes

Mount the assembly upright in a secure, serviceable location with enough clearance to remove and replace the spin-on element. Use diesel-rated fuel hose, fittings, and thread sealing practices suitable for the fuel system. Confirm the inlet and outlet routing before tightening fittings.

After installation or element replacement, use the hand primer pump to purge air from the fuel system according to the engine service procedure. Check all fittings, seals, the bowl, and the filter element for leaks before returning the engine to service.

Parts Desk Insight

The built-in hand primer is the key service advantage on this assembly. It helps remove air after filter changes, which can reduce hard-start issues on diesel systems. The best setup depends on whether the unit is being used as the primary water separator or as a finer secondary filter, so match the replacement element micron rating to the engine’s fuel-system plan.
