Detailed Description
This Sunsong power steering pressure line hose assembly, part number 3401904, is built for 1994 Ford E-350 Econoline and E-350 Econoline Club Wagon models built from 5/1, plus 1995-1996 Ford E-350 Econoline and 1995-1996 Ford E-350 Econoline Club Wagon.

This part cross-references Dayco 80088 and Gates 362990 for the same application.
What It Helps Address
- Power steering fluid leaks from a worn pressure line
- Loss of steering assist caused by hose damage or fatigue
- Corrosion-related failure in steel steering lines
- Improper sealing at the pressure line connection points
- Noisy or inconsistent steering operation linked to pressure loss
Installation Notes and Tips
Verify the vehicle build date before ordering, since 1994 Ford E-350 Econoline and E-350 Econoline Club Wagon coverage applies to vehicles manufactured from 5/1. Confirm the end fittings match the existing steering system: 1/2 in. male inverted flare on one end and 16 mm swivel O-ring on the other. Inspect adjacent steering components, seals, and mounting points before installation to help ensure a clean repair on the Ford E-350 Econoline or E-350 Econoline Club Wagon.
Quality Assurance
Each hose is pressure-tested before it leaves the factory to verify performance and installation readiness. Sunsong states that this hose assembly exceeds original equipment performance standards for pressure, burst strength, and durability.
