Product Overview

The Racor S3227 is the 10-micron replacement spin-on filter element for the Racor 320R series gasoline fuel/water separator assemblies, including the 320R-RAC-01 clear-bowl outboard assembly and the 320R-RAC-02 metal-bowl inboard/sterndrive assembly. Aquabloc® media removes fine particulate contamination and separates free water from gasoline before it reaches the engine. The bowl, bowl O-ring, and drain from the existing assembly are reusable and transfer to the new S3227 element at each service — only the spin-on element itself is replaced.

• 10-micron Aquabloc® filtration media removes particulate and separates free water from gasoline
• Replacement spin-on element for the Racor 320R-RAC-01, 320R-RAC-02, and 490R-RAC-01 assemblies
• Filter head thread: 1"-14
• Max flow: 60 GPH / 227 LPH
• Height: approx. 4.0" / 102 mm | Outside diameter: approx. 3.8" / 97 mm
• Compatible with ethanol-blended gasoline (E10)
• Element only — bowl, O-ring, and drain are separate reusable service components
• Weight: approx. 454 g

Element Only: The S3227 is the replaceable spin-on filter element. The clear bowl (RK30475), bowl O-ring kit (RK22244), and self-venting drain kit (RK30476) are separate reusable components that remain in service and transfer to the new element during routine replacement. If the complete 320R-RAC-01 assembly is needed for a first-time installation, see the Racor 320R-RAC-01 Complete Assembly.

Compatible Applications

• Racor 320R-RAC-01 — clear-bowl outboard/above-deck assembly, 10-micron element replacement
• Racor 320R-RAC-02 — metal-bowl inboard/sterndrive assembly, 10-micron element replacement
• Racor 490R-RAC-01 assembly — 10-micron element replacement
• Compatible Racor 320R-series assemblies using a 1"-14 filter head thread and 60 GPH flow rating

Fitment Note: Confirm the existing assembly uses a 1"-14 filter head thread before ordering. The S3227 is specific to the 320R / 490R series — it is not interchangeable with elements for other Racor filter-head families (e.g., 11/16"-16 or 3/8"-18 NPTF formats).

Service Information

Replace the S3227 per the engine or fuel-system manufacturer’s maintenance schedule, or sooner if fuel restriction symptoms develop, contamination is visible in the bowl, or water accumulation is excessive. Inspect the bowl O-ring (RK22244) at every element change and replace if worn — a degraded O-ring is the most common source of post-service weeping on 320R assemblies.

Installation Notes

• Shut off the fuel supply before beginning element replacement
• Remove the bowl from the old element — inspect the bowl, O-ring (RK22244), and drain for condition; replace the O-ring if worn
• Transfer the serviceable bowl and drain assembly to the new S3227 element
• Lightly lubricate the element thread and sealing surface with clean fuel or a compatible O-ring lubricant
• Thread the S3227 onto the 1"-14 filter head until the sealing surface seats, then hand-tighten — do not over-tighten
• Restore fuel supply, prime the fuel system per the engine manufacturer’s procedure, and inspect all connections and the bowl for leaks before starting the engine

Technical FAQ

What assemblies does the S3227 fit? S3227 fits the Racor 320R-RAC-01 (clear bowl, outboard), the Racor 320R-RAC-02 (metal bowl, inboard/sterndrive), and the 490R-RAC-01 assembly. All use a 1"-14 filter head thread.

Does the S3227 include the bowl? No — the bowl (RK30475), O-ring kit (RK22244), and drain kit (RK30476) are separate reusable components that transfer from the old element to the new S3227 during service.

Is S3227 the same as S3228TUL? No — S3228TUL is the replacement element for the 320R-RAC-02 metal-bowl inboard assembly in some configurations. Confirm the element part number against your specific assembly’s service documentation before ordering.

Is S3227 compatible with E10 gasoline? Yes — Aquabloc® media is compatible with ethanol-blended fuels including E10.

Parts Desk Insights

The S3227 is the go-to routine service element for both the 320R-RAC-01 (outboard/clear bowl) and 320R-RAC-02 (inboard/metal bowl) — making it one of the most commonly ordered Racor replacement elements in the 320R family. The most important clarification is assembly vs. element: if the 320R is already installed and working, the customer needs S3227, not a new 320R-RAC-01 or -02. Bowl O-ring (RK22244) condition should be checked at every element change — a worn O-ring is the most common post-service leak source on 320R assemblies. If a customer reports the S3227 not fitting their existing Racor assembly, confirm the filter head thread — the 320R uses 1"-14, which differs from the 11/16"-16 format used in the B32013/B32020MAM families and the 3/8"-18 NPTF format used in the 660R series.
