Detailed Description
This Sunsong power steering pressure line hose assembly is built to restore hydraulic steering performance in Ford E-350 Club Wagon, Ford E-350 Super Duty, Ford E-350 Econoline Club Wagon, and Ford E-350 Econoline applications with hydroboost systems. Part number 3402520 is engineered to match the original routing and connection style for the pump-to-hydroboost line, helping maintain proper steering assist and hydraulic pressure delivery.
The hose assembly uses CSM hose material and 16 mm swivel O-ring fittings at both ends for the specified fitment. Sunsong also uses high-grade steel tubing with a zinc coating to improve resistance to rust and corrosion from humidity, road salt, water, and grime. The assembly is precision engineered to the listed application and is factory pressure tested before it leaves the plant.
What It Helps Address
- Power steering fluid leaks at the pressure line
- Loss of steering assist from a damaged hose
- Corrosion on the original steel line
- Hydroboost pressure line wear on high-mileage Ford E-350 vehicles
- Noise or inconsistent steering response caused by restricted fluid flow
Installation Notes
Verify hydroboost system configuration before ordering. This hose is listed for pump-to-hydroboost use only, and the fitment notes specify the power steering return line end fitting for the applicable vehicles. Confirm the 16 mm swivel O-ring connection points and the 58.3 in. overall length against the original part before installation.
