Product Overview
The Racor S3232TUL is the 10-micron Aquabloc® replacement spin-on filter element for the Racor 660R-RAC-02 metal-bowl inboard/sterndrive gasoline fuel/water separator assembly. The 660R-RAC-02 is rated at 90 GPH / 341 LPH and uses a reusable metal bowl — required by USCG regulations for below-deck gasoline fuel filter installations. The S3232TUL element is the specified 10-micron replacement for this assembly; at each service, only the spin-on element is replaced while the metal bowl, bowl O-ring, drain plug, and mounting head remain in service.
- 10-micron Aquabloc® media removes water and fine fuel-borne contaminants from gasoline
- Replacement element for the Racor 660R-RAC-02 90 GPH metal-bowl inboard/sterndrive assembly
- Filter head thread: 1"-14
- Height: approx. 5.5" | Diameter: approx. 3.8"
- UL Listed marine application
- Element only — metal bowl, O-ring, drain plug, and mounting head are separate reusable components
- Bowl O-ring kit: RK33544 | Metal bowl kit: RK30473-02
- Weight: approx. 490 g
Element Only: The S3232TUL is the replaceable spin-on filter element. The reusable metal bowl (RK30473-02), bowl O-ring (RK33544), drain plug, and mounting head from the existing 660R-RAC-02 installation transfer to the new element during service. For the complete 660R-RAC-02 assembly, see the Racor 660R-RAC-02.
Below-Deck / Inboard Use: The 660R-RAC-02 uses a metal bowl, which is required by USCG regulations for gasoline fuel filter assemblies installed below deck. The UL Listed S3232TUL element maintains this compliance at each service. For the outboard/above-deck clear-bowl version of the 660R, see the Racor 660R-RAC-01 and its replacement element S3232.
S3232TUL vs. S3232 — Which Do I Need?
- S3232TUL (this part): For the 660R-RAC-02 metal-bowl inboard/sterndrive assembly. UL Listed. Below-deck USCG-compliant installation.
- S3232: For the 660R-RAC-01 clear-bowl outboard/above-deck assembly.
Both are 10-micron elements for the 660R family but are matched to different assemblies. Confirm which assembly is installed before ordering.
Compatible Applications
- Racor 660R-RAC-02 — 90 GPH metal-bowl inboard/sterndrive gasoline fuel/water separator, standard 10-micron element replacement
- Racor 3120R-RAC-32 — in compatible applications per Parker documentation
- Inboard and sterndrive gasoline engine fuel systems using the 660R-RAC-02 metal-bowl assembly
Fitment Note: Confirm the installed assembly is the 660R-RAC-02 (metal bowl, inboard/sterndrive) before ordering. S3232TUL uses a 1"-14 thread and is specific to the 660R-RAC-02 assembly format — it is not interchangeable with elements for the 320R, 490R, or B32013/B32020MAM filter-head families.
Service Information
Replace the S3232TUL per the engine or fuel-system manufacturer’s maintenance schedule, or sooner if fuel restriction symptoms develop, water accumulation in the bowl is excessive, or the filter has been exposed to contaminated fuel. Inspect the bowl O-ring (RK33544) at every element change and replace if worn. Confirm the metal bowl drain plug is tight after reassembly — a loose drain plug is the most common post-service leak point on metal-bowl assemblies.

Installation Notes
- Shut off the fuel supply before beginning element replacement
- Remove the metal bowl from the old element — inspect the bowl and O-ring (RK33544) for condition; replace O-ring if worn
- Transfer the serviceable metal bowl and drain plug to the new S3232TUL element
- Lightly lubricate the element thread and sealing surface with clean fuel or a compatible O-ring lubricant
- Thread the S3232TUL onto the 1"-14 filter head until the sealing surface seats, then hand-tighten — do not over-tighten
- Reinstall the metal bowl drain plug securely before returning to service
- 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
- Confirm installation complies with applicable USCG and ABYC standards for below-deck gasoline fuel systems
Technical FAQ
What is the difference between S3232TUL and S3232? S3232TUL is the replacement element for the 660R-RAC-02 metal-bowl inboard/sterndrive assembly. S3232 is the replacement element for the 660R-RAC-01 clear-bowl outboard assembly. Both are 10-micron for the 660R family, but matched to different assemblies — confirm which is installed before ordering.
Does S3232TUL include the metal bowl? No — the metal bowl (RK30473-02), bowl O-ring (RK33544), and drain plug are separate reusable components that transfer from the old element to the new S3232TUL during service.
Why does the inboard 660R require a metal bowl? USCG regulations require flame-resistant metal bowls for gasoline fuel filter assemblies installed below deck. The 660R-RAC-02 metal bowl and the UL Listed S3232TUL element together maintain this compliance at each service interval.
What is the flow rating of the 660R-RAC-02? The 660R-RAC-02 system is rated at 90 GPH / 341 LPH, making it suitable for high-output inboard and sterndrive gasoline engines.

Parts Desk Insights
The S3232TUL is the inboard/sterndrive counterpart to the S3232 — the most critical fitment check is confirming the customer has the 660R-RAC-02 (metal bowl, inboard) rather than the 660R-RAC-01 (clear bowl, outboard). The TUL suffix distinguishes this from the plain S3232; customers who don’t specify the suffix may be ordering the wrong element for their assembly. Bowl O-ring (RK33544) and drain plug condition should be verified at every element change — the drain plug is the most common post-service leak point on metal-bowl 660R assemblies. The UL Listed designation and USCG metal-bowl requirement are worth confirming for customers certifying a new inboard installation or having work inspected.
