Detailed Description

This Sunsong power steering pressure line hose assembly is built for pressure-side steering fluid transfer in select Ford van applications, including the 1990-1992 Ford E-250 Econoline Club Wagon and Ford E-350 Econoline / E-350 Econoline Club Wagon. Part number 3402107 is made to restore proper steering fluid routing and connection geometry on the listed vehicles, helping maintain consistent steering response and leak-resistant operation.

The hose assembly uses high-grade steel tubing with a zinc coating to improve resistance to humidity, road salt, water, and grime. Its pressure rating and burst strength provide a robust replacement option for aging factory lines, while the exact-fit design supports clean installation on the specified Ford Econoline platforms. This part cross-references Dayco 71847 for the same application.

What This Part Helps Address

• Power steering fluid leaks from a worn or damaged pressure line
• Loss of steering assist caused by pressure-side hose failure
• Corrosion on original steel steering lines
• Cracked, fatigued, or contaminated hose material
• Improper fit from a previous replacement line

Installation Notes and Tips

Verify end fitting style and hose length before installation. This assembly uses a 1/2 in male inverted flare on one end and a 16 mm male O-ring on the other, with no bracket and no power steering switch port. Confirm routing and connection points against the original line on your Ford E-250 Econoline Club Wagon or Ford E-350 Econoline before tightening fittings.

Quality Assurance

Each Sunsong 3402107 hose is pressure-tested before it leaves the factory to confirm proper operation and installation readiness. The construction is intended to deliver long service life in demanding steering system conditions.
