Product Overview

The Racor S3240 is the 10-micron Aquabloc® replacement fuel filter/water separator element for the Racor 120R-RAC-01 compact clear-bowl outboard gasoline fuel/water separator, rated at up to 30 GPH / 114 LPH. Unlike most Racor replacement elements, the S3240 includes the required head gasket and bowl O-ring in the package, so no separate seal kit is needed for standard element service. Aquabloc® media removes approximately 99% of free water and fine particulate contamination from gasoline before it reaches the engine. The reusable clear bowl, drain, and mounting head remain in service and transfer to the new element.

• 10-micron nominal Aquabloc® media removes approximately 99% of free water and sediment
• Replacement element for the Racor 120R-RAC-01 compact clear-bowl outboard 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
• Max system flow: 30 GPH / 114 LPH
• Meets ABYC standard for gasoline-powered vessels
• Corrosion-resistant construction
• Element only — clear bowl and drain are separate reusable components (bowl kit: RK10222)
• Weight: approx. 794 g (packaged)

Outboard / Above-Deck Use Only: The 120R-RAC-01 uses a clear bowl, which is approved for outboard and above-deck gasoline installations. For below-deck inboard installations requiring a metal bowl, the 120R-RAC-02 and its replacement element S3240TUL are the appropriate choice.

S3240 vs. S3240TUL — Which Do I Need?

• S3240 (this part): For the 120R-RAC-01 clear-bowl outboard assembly. Includes head gasket and bowl O-ring.
• S3240TUL: For the 120R-RAC-02 metal-bowl inboard/below-deck assembly.

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

Compatible Applications

• Racor 120R-RAC-01 — compact clear-bowl outboard gasoline fuel/water separator, standard 10-micron element replacement
• Outboard gasoline engine fuel systems using the 120R-RAC-01 assembly with up to 30 GPH fuel-flow demand
• Above-deck gasoline installations requiring a compact 10-micron water-separating replacement element

Fitment Note: Confirm the installed assembly is the 120R-RAC-01 (clear bowl, M18 x 1.5 thread) before ordering. S3240 and S3240TUL both use an M18 x 1.5 thread but are specified for different assemblies — do not select by appearance alone.

Kit Contents

• S3240 replacement filter element (10 micron Aquabloc®)
• Head gasket
• Bowl O-ring

The reusable clear bowl and drain assembly remain in service. If the bowl or drain requires replacement, order the RK10222 clear bowl kit or RK30476 self-venting drain kit separately.

Service Information

Replace the S3240 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 contamination is visible. Inspect the clear bowl at each service for haze, cracking, or deformation — replace the bowl (RK10222) if any damage is found. The included head gasket and bowl O-ring should be replaced at each element change.

Part Number Reference

• Clear bowl kit: RK10222
• Self-venting drain kit: RK30476

Installation Notes

• Shut off the fuel supply before beginning element replacement
• Remove the clear bowl from the old element — inspect the bowl for haze, cracking, or deformation; replace if damaged (RK10222)
• Install the included bowl O-ring on the new S3240 element
• Install the included head gasket on the filter head sealing surface
• Thread the S3240 onto the M18 x 1.5 filter head until the sealing surface seats, then hand-tighten — do not over-tighten
• Reattach the clear bowl securely
• 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 S3240 fit? The S3240 is the replacement element for the Racor 120R-RAC-01 compact clear-bowl outboard gasoline fuel/water separator, rated at 30 GPH. Confirm the installed assembly before ordering.

Does the S3240 include seals? Yes — the S3240 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 clear bowl itself needs replacement, order RK10222.

What is the difference between S3240 and S3240TUL? S3240 is for the 120R-RAC-01 clear-bowl outboard assembly and includes the head gasket and bowl O-ring. S3240TUL is for the 120R-RAC-02 metal-bowl inboard assembly. Both use an M18 x 1.5 thread but are specified for different assemblies.

How does the 120R-RAC-01 compare to the 320R-RAC-01? The 120R-RAC-01 (S3240 element, 30 GPH) is a compact unit for smaller outboard engines with lower fuel-flow demand. The 320R-RAC-01 (S3227 element, 60 GPH) handles higher flow for larger single outboard engines. Confirm the engine’s fuel-flow requirement before selecting a separator assembly.

Parts Desk Insights

The S3240 is the compact entry-level Racor gasoline element — the 120R-RAC-01 is a 30 GPH unit suited to smaller outboards where a full 320R or 660R assembly is oversized. The key differentiator from other Racor gasoline elements is that S3240 includes the head gasket and bowl O-ring in the package — worth confirming with the customer so they don’t separately order a seal kit they don’t need. The S3240 vs. S3240TUL distinction follows the same clear-bowl/metal-bowl outboard/inboard pattern as the rest of the Racor gasoline line — confirm which assembly is installed before recommending. If a customer reports needing more flow than the 120R provides, the next step up is the 320R-RAC-01 (60 GPH) with the S3227 element.
