What It Helps Address

• Leaking or cracked power steering return hose
• Fluid seepage at the hydroboost-to-pump return path
• Hose routing issues caused by a damaged OE line
• Steering-system contamination from deteriorated hose material
• Fitment problems when replacing a worn return line on hydroboost-equipped trucks and SUVs

Installation Notes

Verify hydroboost configuration before ordering, especially on vehicles noted with dual return tubes on the reservoir. Compare the original hose routing, end connections, and available clearance before installation. This part is intended for the Hydroboost To Pump position and should be matched to the vehicle’s steering layout.

Edelmann designs this Return Line Assembly to meet or exceed OE specifications for routing, construction, and durability. The hose is engineered to handle steering-system heat and pressure pulsations while helping maintain clean fluid flow in the power steering system.
