Edelmann 91566 Power Steering Pressure Line Hose Assembly - Pump To Hydroboost

Edelmann 91566 Pressure Line Assembly

The Edelmann 91566 pressure line assembly is built for power steering systems that route from the pump to the hydroboost unit. It is formed to follow OE hose routing and uses materials selected to handle steering-system pressure pulsations and heat.

For 1976-1979 Cadillac applications, this hose supports a precise replacement for the original pressure line layout. The 53-inch hose length helps match the factory routing on Seville, Eldorado, Commercial Chassis, and Fleetwood models equipped with hydroboost steering assist.

Key Features

• Pressure line hose assembly for pump-to-hydroboost routing
• 53-inch hose length
• OE-style routing for a direct replacement fit
• Built to resist heat and pressure pulsation in steering systems
• Constructed to help reduce premature hose breakdown and contamination

Detailed Description

Edelmann Pressure Line Assembly 91566 is engineered as a power steering pressure line hose assembly for Cadillac vehicles using a hydroboost system. The hose is shaped to duplicate the original routing so it installs in the intended space without unnecessary rework. This makes it a practical replacement for service on 1978-1979 Cadillac Seville, 1976-1978 Cadillac Eldorado, 1976 Cadillac Commercial Chassis, and 1976 Cadillac Fleetwood with pump-to-hydroboost routing. This part cross-references Gates 364040 for the same application.

The Pressure Line Assembly product line focuses on OE-style hose construction for steering systems where routing accuracy and pressure resistance matter. Part number 91566 is designed for long-term service in demanding hydraulic steering environments.

Vehicle Fitment

Common Replacement Uses

• Leaking power steering pressure hose at the pump-to-hydroboost connection
• Cracked or heat-damaged steering hose routing
• Loss of steering assist caused by pressure line failure
• Fluid contamination from deteriorated hose material
• Incorrect fitment from a hose that does not match OE routing

Installation Notes

Verify the vehicle uses a hydroboost steering system before installation. Compare the original hose routing, end connections, and reservoir configuration to confirm the replacement matches the factory layout. Inspect adjacent steering components for wear or leakage before returning the vehicle to service.

Quality Assurance

Edelmann designs this pressure line assembly to meet or exceed OE specifications for fit and function. The hose is manufactured to handle steering-system pressure and heat while maintaining the routing needed for a clean installation.
