CARMOCAR Fuel Filter Water Separator Assembly S3227 — 3/8" Barb x 1/4" NPT, 10‑Micron Clear Bowl

CARMOCAR S3227 is a plug-and-play fuel filter water separator assembly designed to trap water and contaminants from gasoline and diesel before they reach your engine. The S3227 combines a clear collection bowl, a 10-micron synthetic filter element and 3/8" barb x 1/4" NPT fittings to provide reliable inline fuel filtration for small engines, especially outboard marine motors. Built from corrosion-resistant materials and intended as a direct replacement for several common part numbers, this assembly simplifies servicing and adds visible water separation so you can inspect and drain contaminants without disassembly.

How does the S3227 protect my engine during operation?

The assembly captures water droplets and solid particles that damage fuel pumps, injectors and carburetors. Its synthetic 10-micron filter media removes fine debris while the clear bowl separates and collects free water for easy inspection and draining.

• 10-micron synthetic filter element reduces abrasive wear on fuel-system components
• Clear bowl lets you see water and sediment buildup at a glance
• Durable housing resists corrosion, leakage and pressure from fuel systems

Will this part fit my engine and replace the same OEM numbers?

The S3227 is made as a universal-style replacement and lists several equivalent part numbers to help compatibility planning. Check the physical fittings and mounting location on your engine—this kit uses a 3/8" barb inlet/outlet with a 1/4" NPT thread where shown.

• Replaces common references: S3227, 18-7948, 9-37882 and related filter/bowl numbers
• Includes the full assembly with clear bowl and specified fittings for direct swap
• Designed for outboard and other small engine fuel applications—verify fit before purchase

How easy is installation and routine maintenance?

Installation is intended to be straightforward: the S3227 is a plug-and-play assembly that does not require electrical changes. Periodic maintenance consists of visually checking the bowl, draining collected water and replacing the filter element according to hours of operation or visible contamination.

• Direct installation: no wiring modifications, simple hose and thread connections
• Clear bowl enables quick visual checks and manual draining of separated water
• Filter replacement is a serviceable cartridge; follow engine-maker intervals for best results

What materials and build quality should I expect?

The housing and bowl are produced from materials formulated to withstand fuel exposure, friction and pressure typical of marine and small engine environments. The internal filter uses synthetic fiber media for consistent particle removal and longevity under normal conditions.

• Corrosion-resistant housing minimizes long-term fuel exposure damage
• Synthetic 10-micron media balances filtration efficiency with flow requirements
• Clear collection bowl manufactured to resist staining and allow easy inspection

This assembly is ideal for boat owners, small-engine technicians and anyone needing a visible, serviceable fuel filter/water separator without electrical changes. If you operate outboard engines, lawn or garden equipment, or portable generators and you want to reduce the risk of fuel-related downtime, the CARMOCAR S3227 offers a practical, replaceable solution—verify fitting sizes and OEM references against your existing unit before ordering.

FAQ
