Key Features

• OE-style routing for a precise hose path and clean fitment
• Built for high-pressure steering system pulsations and heat exposure
• Constructed with materials selected to resist premature hose breakdown
• Pressure line assembly for pump-to-hydroboost applications
• Hose length: 52.25 inches

Detailed Description

Edelmann 91866 is a power steering pressure line hose assembly for Chevrolet and GMC trucks and vans with pump-to-hydroboost routing. It is built to duplicate the original hose trajectory, which helps the line fit the allotted space without forcing bends or creating unnecessary stress points. The 91866 part number is associated with a broad range of 1985-1991 Chevrolet and GMC applications, including C/K and R/V series models.

As a pressure line assembly, this hose is intended for the high-pressure side of the steering system, where heat and pulsation can accelerate wear. The design focuses on maintaining system integrity and reducing the risk of contamination from hose breakdown. This part cross-references Four Seasons 36663 and Gates 366630 for the same application.

What It Is Used For

• Replacing a leaking or deteriorated power steering pressure hose
• Restoring proper pump-to-hydroboost fluid transfer
• Addressing hose routing issues caused by incorrect bends or fitment
• Correcting steering system noise or performance loss related to pressure-line wear
• Replacing a hose affected by heat, pulsation, or age-related breakdown

Installation Notes and Tips

Verify the vehicle’s pump-to-hydroboost configuration before ordering. This hose is fitment-specific and should be matched to the exact application listed for Chevrolet and GMC C/K, R, and V series models. Confirm the hose path and connection points against the original line to ensure proper routing during installation.

Quality Assurance

Edelmann states that this pressure line assembly is manufactured to match or exceed original equipment specifications. The design emphasis on OE routing, material selection, and resistance to pressure and heat supports consistent installation and dependable service life.
