Product Overview

The Racor S3240TUL is the 10-micron Aquabloc® replacement spin-on filter element for the Racor 120R-RAC-02 compact metal-bowl gasoline fuel/water separator, rated at up to 30 GPH / 114 LPH. Like the S3240 for the clear-bowl 120R-RAC-01, the S3240TUL includes the required head gasket and bowl O-ring in the package, so no separate seal kit is needed for standard element service. The reusable metal bowl and mounting head remain in service and transfer to the new element at each service interval.

• 10-micron Aquabloc® media removes water and fine fuel-borne contaminants from gasoline
• Replacement element for the Racor 120R-RAC-02 compact metal-bowl gasoline separator
• Includes head gasket and bowl O-ring — no separate seal kit required for standard element service
• Filter head thread: M18 x 1.5
• Height: approx. 2.5" | Diameter: approx. 3.0"
• Max system flow: 30 GPH / 114 LPH
• UL Listed / USCG approved
• Element only — metal bowl is a separate reusable component (bowl kit: RK10226)
• Weight: approx. 400 g (packaged with gasket and O-ring)

Element Only: The S3240TUL is the replaceable spin-on filter element. The reusable metal bowl (RK10226) and mounting head from the existing 120R-RAC-02 installation remain in service and transfer to the new element during service. The included head gasket and bowl O-ring replace the worn seals at each element change.

S3240TUL vs. S3240 — Which Do I Need?

• S3240TUL (this part): For the 120R-RAC-02 metal-bowl assembly. UL Listed. Suitable for inboard and outboard installations. Includes head gasket and bowl O-ring.
• S3240: For the 120R-RAC-01 clear-bowl outboard/above-deck assembly. Also includes head gasket and bowl O-ring.

Both use an M18 x 1.5 center thread but are specified for different assemblies. Confirm which assembly is installed before ordering.

Compatible Applications

• Racor 120R-RAC-02 — compact metal-bowl gasoline fuel/water separator, standard 10-micron element replacement
• Inboard and outboard gasoline engine fuel systems using the 120R-RAC-02 metal-bowl assembly
• Installations requiring a UL Listed / USCG-approved replacement element in a compact 30 GPH gasoline separator

Fitment Note: Confirm the installed assembly is the 120R-RAC-02 (metal bowl, M18 x 1.5 thread) before ordering. S3240TUL and S3240 look similar and share the same thread, but are specified for different 120R assemblies.

Kit Contents

• S3240TUL replacement filter element (10 micron Aquabloc®)
• Head gasket
• Bowl O-ring

The reusable metal bowl remains in service. If the bowl requires replacement, order the RK10226 metal bowl kit separately.

Dimensions

• Height: approx. 2.5" / 64 mm
• Outside diameter: approx. 3.0" / 76 mm
• Center thread: M18 x 1.5
• Max flow: 30 GPH / 114 LPH

Service Information

Replace the S3240TUL per the engine or fuel-system manufacturer’s maintenance schedule, or sooner if fuel restriction symptoms develop, water accumulation is excessive, or contaminated fuel has entered the system. Inspect the metal bowl at each service and replace if damaged (RK10226). The included head gasket and bowl O-ring should be replaced at each element change — do not reuse the old seals.

Part Number Reference

Installation Notes

• Shut off the fuel supply before beginning element replacement
• Remove the metal bowl from the old element — inspect the bowl for damage; replace if worn (RK10226)
• Install the included bowl O-ring on the new S3240TUL element
• Install the included head gasket on the filter head sealing surface — do not reuse the old gasket
• Thread the S3240TUL onto the M18 x 1.5 filter head until the sealing surface seats, then hand-tighten — do not over-tighten
• Reattach the metal bowl securely; confirm the drain plug (if equipped) is tight
• 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 assembly does the S3240TUL fit? The S3240TUL is the replacement element for the Racor 120R-RAC-02 compact metal-bowl gasoline fuel/water separator (30 GPH, M18 x 1.5 thread). Confirm the installed assembly before ordering.

Does the S3240TUL include seals? Yes — the S3240TUL includes the head gasket and bowl O-ring required for standard element service. No separate seal kit is needed at routine element changes. If the metal bowl itself requires replacement, order RK10226.

What is the difference between S3240TUL and S3240? S3240TUL is for the 120R-RAC-02 metal-bowl assembly (inboard and outboard use, UL Listed). S3240 is for the 120R-RAC-01 clear-bowl outboard assembly. Both use an M18 x 1.5 thread and include seals, but are specified for different assemblies.

How does the 120R-RAC-02 compare to the 320R-RAC-02? The 120R-RAC-02 (S3240TUL element, 30 GPH) is a compact unit for smaller engines with lower fuel-flow demand. The 320R-RAC-02 (S3228TUL element, 60 GPH) handles higher flow for larger inboard and sterndrive engines. Confirm the engine’s fuel-flow specification before selecting an assembly.

Parts Desk Insights

The S3240TUL is the metal-bowl counterpart to the S3240 — both are compact 30 GPH 120R elements that include the head gasket and bowl O-ring, which is worth confirming with customers so they don’t separately order a seal kit they don’t need. The TUL vs. plain suffix distinction is the same clear-bowl/metal-bowl pattern that runs through the entire Racor gasoline line (S3228TUL/S3228SUL, S3232/S3232TUL) — confirm the bowl type of the installed assembly before recommending. The UL Listed / USCG-approved designation is important for inboard customers or those with inspected vessels. Remind customers that the old head gasket should never be reused — the included replacement gasket is there for a reason, and reusing a compressed gasket is a common post-service leak source on the 120R family.
