HIMARKLIF Outboard Fuel Connector for Suzuki & Johnson/Evinrude — Replacement for OEM 65720-986B0 / Brass-Core PA Body

HIMARKLIF Outboard Fuel Connector is a replacement fuel line coupler designed to fit Suzuki DF 4–140 HP and select Johnson/Evinrude/Sierra outboard engines, providing a durable, tool-free connection for marine fuel systems.

If you maintain outboard motors, a reliable fuel connector prevents leaks, eases servicing, and speeds up engine swaps. This HIMARKLIF connector replaces OEM part numbers 65720-986B0, 65720-986L0, 5032150 and Sierra 18-80425, and is engineered to match the bore and pressure requirements of many two- and four-stroke Suzuki and Johnson/Evinrude outboards. Built from PA plastic with a brass inner core, it balances chemical resistance with mechanical strength so it stands up to fuel exposure and repeated use.

Which engines and part numbers does this connector replace?

This connector is manufactured to be compatible with a wide range of outboard engines and specific OEM part numbers so you can replace worn or damaged couplers without modifying fuel lines. It directly corresponds to Suzuki and Johnson/Evinrude items used across multiple horsepower ratings.

• Compatible with Suzuki DF 4, 5, 6, 8, 9.9, 15, 25, 30, 40, 50, 60, 70, 90, 100, 115, and 140 HP models.
• Fits Johnson and Evinrude outboards that use part number 5032150.
• Matches Sierra part number 18-80425 for cross-reference replacements.
• Replaces Suzuki OEM 65720-986B0 and 65720-986L0 to ensure proper fit.

How durable and resistant is the HIMARKLIF fuel connector?

The connector combines a PA (polyamide) plastic outer body with a brass core to resist fuel, oil, and pressure common in marine environments. This construction reduces the chance of cracking, swelling, or corrosion that can cause leaks over time.

• PA plastic body offers high oil and chemical resistance for prolonged exposure to gasoline and additives.
• Brass core provides strength and corrosion resistance where metal reinforcement is needed.
• Designed to withstand typical marine fuel pressures and repeated connect/disconnect cycles.
• Long service life reduces frequency of part replacements during maintenance.

Is installation straightforward and what tools are required?

Yes — the connector is manufactured to standard bore specifications so it plugs into existing fuel lines without modifications or special tools. Quick connect/disconnect functionality speeds routine maintenance and rigging changes on the water.

• Standard bore sizing allows push-fit installation with compatible fuel tubing.
• No specialty tools required for standard installation or removal.
• Ideal for field repairs, winterization prep, or replacing aged couplers.
• Package includes one outboard fuel connector ready for immediate use.

What should I check before buying this connector?

Verify your engine model and OEM part number to ensure compatibility. Also inspect hose inner diameter and fuel line condition so the new connector can be seated securely and function safely under pressure.

• Confirm the OEM replacement numbers: 65720-986B0, 65720-986L0, 5032150, 18-80425.
• Measure your fuel hose inner diameter to match the connector bore for a snug fit.
• Replace cracked or hardened fuel lines when fitting a new connector to prevent leaks.
• Test for secure engagement and check for leaks before returning the engine to service.

Who is this for: The HIMARKLIF Outboard Fuel Connector is made for boat owners, marine mechanics, and weekend anglers who need a reliable OEM-compatible coupler for Suzuki and compatible Johnson/Evinrude engines. It’s well-suited for routine maintenance, mid-season repairs, and fleet managers who prefer a durable, easy-to-install replacement part that matches original specifications.
