This hose is designed for low-pressure return flow while handling elevated temperatures, making it a direct-service replacement for worn, leaking, or corroded return hoses on the 2000-2003 Ford F-250 Super Duty and 2000-2003 Ford F-350 Super Duty. The assembly uses high-grade steel tubing with zinc electroplating for added resistance to rust, road salt, humidity, water, and grime. Part number 3404912 is built to restore the original hose path and connection style without changing the factory steering layout.\u003c\/p\u003e\u003cp\u003eThis part cross-references Ford YC3Z3A713BA for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Fix\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower steering fluid seepage from a deteriorated return hose\u003c\/li\u003e\n\u003cli\u003eCorrosion on the original steel line\u003c\/li\u003e\n\u003cli\u003eNoise or inconsistent steering assist caused by restricted return flow\u003c\/li\u003e\n\u003cli\u003eDamage from heat, moisture, road salt, and grime exposure\u003c\/li\u003e\n\u003cli\u003eIncorrect hose routing or poor fit from a worn replacement line\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the end fittings before installation: one end uses a 16 mm male connection and the other uses a 3\/8 in. bubble flare. Confirm the vehicle is equipped with the gear-to-cooler return line layout before ordering. Inspect adjacent steering components, clamps, and mounting points for wear or corrosion so the replacement line can seat correctly and maintain proper routing.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eSunsong states that this return hose exceeds original equipment performance standards for return-line service and is manufactured with corrosion-resistant steel tubing and protective zinc coating for long-term durability.\u003c\/p\u003e","brand":"Sunsong","offers":[{"title":"Default Title","offer_id":52845352878261,"sku":"FTTD-3404912","price":47.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/S5_3404912_Fro.jpg?v=1784789206","url":"https:\/\/www.partcatalog.com\/products\/sunsong-3404912-power-steering-return-line-hose-assembly-gear-to-cooler","provider":"PartCatalog","version":"1.0","type":"link"}
