SeaSierra Outboard Fuel Line Connector 3/8" for Suzuki DF 4–140 HP — Brass-coated, OEM-fit

The SeaSierra 65750-87J11 is a 3/8" outboard fuel line connector built to replace Suzuki OEM fittings and restore reliable fuel flow for DF 4–140 HP engines.

Designed for routine maintenance and emergency repairs, this fuel connector matches multiple Suzuki DF models and replaces OEM part numbers 65750-87JL0, 65750-87J11, 65750-87J10, and 65750-87J00 (Sierra 18-80419). It pairs a molded high-grade plastic core with an outer brass coating to combine lightweight resilience with improved corrosion resistance—useful for saltwater and freshwater applications.

• Connector size: 3/8" fuel line inner diameter

How durable is the SeaSierra fuel line connector for marine use?

This connector was engineered for marine conditions by combining a sturdy plastic inner body with a protective brass outer coating. That construction reduces the chance of degradation from vibration and exposure while keeping the component lightweight.

• High-grade plastic core resists cracking and fuel swelling
• Outer brass finish improves corrosion resistance in saltwater
• Designed to withstand typical engine vibrations and movement
• Meets the demands of routine boating and seasonal storage

What should I know about installation and fitment?

Installation is straightforward for anyone familiar with outboard fuel lines: confirm the 3/8" hose size, remove the old fitting, and secure the connector with suitable clamps. No special tools are required, but inspect hose ends and clamps for wear during replacement to ensure a safe, leak-free connection.

• Verify 3/8" inner diameter fuel hose before fitment
• Use marine-grade hose clamps or crimp-type fittings for secure seals
• Replace worn hose or clamps when installing the connector
• Check for leaks after a short run prior to regular use

Why choose this SeaSierra part instead of another aftermarket connector?

SeaSierra focuses on practical replacement parts that match OEM fit and function without unnecessary cost. This connector covers many Suzuki models, uses corrosion-resistant materials, and is a direct, cross-referenced replacement for common Suzuki OEM numbers.

• Direct replacement for Suzuki OEM part numbers for quick compatibility
• Durable mixed-material construction for marine environments
• Cost-effective option for fleet owners and recreational boaters
• Compact design preserves routing and clearance found in OEM fittings

Who is this for: The SeaSierra 65750-87J11 connector is ideal for boat owners, mechanics, and marinas needing an OEM-equivalent fuel fitting for Suzuki DF outboards from small portable motors up to 140 HP. It suits those who want an affordable, corrosion-resistant replacement that’s easy to install during routine maintenance or while performing a swift field repair.
