Sunsong 3405188 Power Steering Return Line Hose Assembly - Gear To Pipe

Sunsong 3405188 Power Steering Return Hose

Sunsong 3405188 is a power steering return line hose assembly built for low-pressure, high-temperature return-side service. It is engineered for exact fit on select Mitsubishi applications and uses corrosion-resistant steel tubing with a zinc coating to help stand up to humidity, road salt, water, and grime.

For Mitsubishi Eclipse, Galant, and Endeavor steering repairs, this return hose assembly restores the return path between the gear and pipe with OE-style fitment and durable CSM hose construction.

Key Features

• Power steering return line hose assembly for return-side steering service
• Max working pressure of 250 psi for low-pressure hydraulic operation
• CSM hose material for heat and fluid resistance
• Steel tubing with zinc plating for added corrosion and rust resistance
• End 1: 16 mm male O-ring fitting
• End 2: 9.6 mm ID hose connection
• Direct-fit design for gear-to-pipe routing
• Part number: 3405188

Detailed Description

This Sunsong power steering return line hose assembly is built to replace worn or damaged return hoses on Mitsubishi steering systems. It is designed for the gear-to-pipe position and follows the original routing and connection style for a precise fit. The hose assembly is suitable for low-pressure, high-temperature return applications and is constructed to exceed original equipment performance standards in this service area. Part number 3405188 is a practical replacement when the original hose shows leaks, cracking, or corrosion.

Compatible With 2006-2012 Mitsubishi Eclipse, Gear To Pipe; 2004-2012 Mitsubishi Galant, Gear To Pipe; and 2004-2011 Mitsubishi Endeavor, Gear To Pipe. This part cross-references Gates 366813 for the same application.

What It Helps Fix

• Power steering fluid leaks at the return hose
• Cracked, hardened, or heat-damaged hose material
• Corrosion on steel tubing and fittings
• Steering noise caused by low fluid level from hose seepage
• Loss of steering assist from a compromised return line

Installation Notes

Verify the vehicle’s steering routing, end fitting sizes, and gear-to-pipe configuration before installation. Inspect adjacent brackets, grommets, heat shields, bushings, and protective sleeves during service and replace any worn components as needed to restore the steering system to original condition. Confirm the hose path is clear of moving parts and heat sources after installation.

Quality Assurance

Sunsong manufactures this hose assembly with high-grade steel tubing and zinc coating for improved resistance to rust and environmental exposure. The design follows exact-fit requirements for the listed Mitsubishi applications and is built for return-side steering service at up to 250 psi working pressure.
