Hoymi high-pressure fuel filter for Suzuki 6-cylinder 4-stroke DF200–DF300 — 10-micron, 98% efficiency with bracket

HOYMI 15440-90J00 high-pressure fuel filter is a direct-fit replacement for Suzuki 6-cylinder 4-stroke outboards, delivering 10-micron filtration and OEM-equivalent sealing for DF90–DF300 engines.

Keep your Suzuki outboard's fuel system free from abrasive debris and contaminants with a filter engineered to match original equipment fit, form, and function. This HOYMI high-pressure assembly cross-references Suzuki part numbers 15440-90J00 and 15440-93J00 (also listed as 5033704 / 5034985) and is designed for 6-cylinder, 4-stroke DF200/DF225/DF250/DF300 and compatible DF90–DF140 models built between 2004 and 2012. Built to withstand repeated pressure impulses and outfitted with a mounting bracket and 5/16-inch (8 mm) connections, it helps maintain consistent fuel flow to the engine's injection system.

How does this filter protect my outboard's fuel system?

The HOYMI filter traps microscopic particles that can damage injectors and pumps, reducing the risk of performance degradation. Rated at 10 microns and tested to 98% filtration efficiency, it captures most common contaminants carried by marine fuel.

• 10-micron media for fine particle capture
• 98% filtration efficiency to reduce injector wear
• High-pressure design suitable for modern fuel-injected outboards
• Bracket and 5/16-inch inlet/outlet for secure plumbing

Will this unit fit my Suzuki engine and replace the OEM part?

This HOYMI assembly is produced to match OEM specifications and is interchangeable with Suzuki part numbers 15440-90J00 and 15440-93J00 (5033704 / 5034985). It is intended for Suzuki 6-cylinder 4-stroke DF200 series and compatible DF90–DF140 models from the specified years, so check your engine's part reference before ordering.

• Interchangeable with Suzuki OEM numbers listed
• Designed for DF200, DF225, DF250, DF300 and compatible DF90–DF140
• Compatible with 6-cylinder 4-stroke fuel systems (2004–2012 applications)
• Includes mounting bracket and standard 5/16" fittings for installation

How durable is the filter under marine operating conditions?

Durability is built into the HOYMI filter: the assembly is tested to withstand 100,000 pressure-impulse cycles without leakage, which helps ensure a long service life under fluctuating fuel pressures. The housing and seals are engineered for repeated use in marine environments where vibration and pressure changes are common.

• 100,000-cycle pressure impulse test for leak resistance
• Robust housing and sealing materials for marine durability
• Stable filtration performance across a range of operating pressures
• Corrosion-resistant bracket for secure mounting on the engine

What should I expect when installing and maintaining this filter?

Installation follows the same routing as the OEM filter; the included bracket and 5/16-inch connections simplify plumbing and mounting. Regular replacement intervals depend on fuel quality and operating hours, but inspecting the element during routine service helps prevent clogged lines and poor engine response.

• Direct-fit design for easy swap with OEM filter
• Comes with bracket for secure attachment to engine mounts
• Standard 5/16" (8 mm) fittings for fuel hose compatibility
• Inspect during scheduled maintenance and replace when flow is reduced

Who this is for: boat owners, marine technicians, and DIYers running Suzuki 6-cylinder 4-stroke outboards who need a reliable, OEM-compatible high-pressure fuel filter. If you want a replacement that matches Suzuki part references, offers fine 10-micron filtration, and is built for repeated pressure cycles with a mounting bracket included, this HOYMI unit is designed for your engine maintenance and seasonal servicing needs.
