Sunsong 3404603 is a power steering reservoir hose for the reservoir-to-pump circuit on select Acura and Honda applications. It is built for low-pressure, high-temperature return flow and is engineered to match the original routing and fit of the OE hose.

Key Features

• Return hose for reservoir to pump steering fluid flow
• Rated for up to 250 psi working pressure
• Built for low-pressure, high-temperature operation
• Steel tubing with zinc electroplating for corrosion and rust resistance
• Precision-engineered fit for original-style routing
• Includes required brackets, grommets, heat shields, bushings, and protective sleeves as specified for the application

Application Details

Compatible with 2010-2014 Acura TSX, reservoir to pump; 2008-2012 Honda Accord, reservoir to pump; 2012 Honda Crosstour, reservoir to pump; 2010-2011 Honda Accord Crosstour, reservoir to pump; and 2008 Acura TL, reservoir to pump. This part number, 3404603, also cross-references 53731TA6A00 for the same application.

The hose is manufactured to restore the wearable components associated with the steering return line to original condition. For Acura TSX, Honda Accord, and Honda Crosstour service work, 3404603 provides an OE-style replacement path where correct routing, corrosion resistance, and pressure handling matter.

What It Helps Fix

• Power steering fluid seepage at the reservoir-to-pump line
• Cracked, rusted, or corroded return hose tubing
• Noise or poor steering assist caused by fluid loss
• Incorrect hose routing or fit after prior repairs
• Heat-related deterioration in the steering return circuit

Installation Notes

Verify vehicle year, make, model, and reservoir-to-pump routing before installation. Inspect adjacent steering components, mounting points, and protective sleeves for wear, and replace any damaged related parts during service. Follow factory service procedures for fluid bleeding and leak checks after installation.
