- Compatible with 1977 Ford F-250 applications
- 5/8 in female end and 1/2 in male inverted flare end
- 45.3 in overall length for OE-style routing
- CSM and steel construction for strength and fluid resistance
- Steel tubing with zinc coating for added corrosion and rust resistance
- Pressure rated to 1,500 psi working pressure, 8,700 psi burst pressure, and 1,600 lb tensile strength
Detailed Description
Sunsong 3401983 is a replacement power steering pressure line hose assembly for the 1977 Ford F-250. It is built to match original routing and connection points, with a 5/8 inch female fitting on one end and a 1/2 inch male inverted flare fitting on the other. The 45.3 inch length supports proper fitment in the steering system layout used on this truck.
The hose assembly combines CSM hose material with steel tubing and a zinc-plated finish to resist corrosion from humidity, road salt, water, and grime. This construction helps maintain steering pressure delivery while replacing worn or damaged pressure lines on the Ford F-250. This part cross-references Gates 366810 for the same application.
What It Helps Fix
- Power steering fluid leaks from a cracked or worn pressure line
- Loss of steering assist caused by pressure loss in the hose assembly
- Corrosion damage on steel steering line tubing
- Hard steering caused by restricted or failing pressure hose flow
- Noise or fluid seepage from deteriorated hose connections
Installation Notes and Tips
Verify fitting sizes, hose routing, and vehicle build date before installation. This part is listed for 1977 Ford F-250 applications, including notes for vehicles from 4/1. Confirm the existing line matches the 5/8 inch female and 1/2 inch male inverted flare connection style before replacement.
Inspect related steering components, seals, and fluid condition during service to help ensure proper operation after installation. Part number 3401983 is intended for direct replacement use in the specified Ford F-250 application.
Quality Assurance
Each Sunsong pressure hose is high-pressure tested before leaving the factory to support consistent operation and installation. The manufacturer states this hose assembly exceeds original equipment performance standards for pressure, burst strength, and tensile strength.
