Edelmann 70404 Power Steering Pressure Line Hose Assembly - Pump To Tee

Edelmann 70404 Pressure Line Assembly

The Edelmann 70404 power steering pressure line hose assembly is built for direct replacement on select GM rear-wheel-drive applications with air conditioning. It is engineered to match OE routing and dimensions, including a 28.375-inch hose length, for a precise installation in the available space.

Designed for pressure-side steering service, this Pressure Line Assembly is made to handle the heat and pulsation common in power steering systems while helping reduce the risk of premature hose breakdown and fluid contamination.

Key Features

• Part number 70404 power steering pressure line hose assembly
• 28.375-inch hose length
• OE-style routing for a direct-fit installation
• Built for pressure pulsations and elevated steering-system temperatures
• Constructed with materials selected to help resist premature failure
• Compatible with pump-to-tee steering line applications

Application Details

Compatible with 1985-1988 Chevrolet Caprice, pump to tee; 1986-1988 Chevrolet Monte Carlo, pump to tee; 1986-1987 Buick Regal, pump to tee; 1986-1987 Chevrolet El Camino, pump to tee; 1986-1987 Oldsmobile Cutlass, pump to tee; 1987 Oldsmobile Cutlass Salon, pump to tee; 1986-1987 Oldsmobile Cutlass Supreme, pump to tee; 1986-1987 Pontiac Grand Prix, pump to tee; 1986 Pontiac Bonneville, pump to tee; and 1986 Pontiac Parisienne, pump to tee. These applications are noted for vehicles with air conditioning, and the line is shaped to follow the original hose path for proper clearance.

This part cross-references FEL-PRO 35719 and Gates 357190 for the same application.

What It Helps Fix

• Power steering fluid leaks from a worn pressure hose
• Cracked or hardened hose material from heat exposure
• Steering noise caused by pressure loss in the line
• Routing issues after a failed or incorrect replacement hose
• Contamination concerns from deteriorating hose internals

Installation Notes

Verify the vehicle’s pump-to-tee routing, air conditioning configuration, and engine-specific fitment before installation. Compare the original hose path to the Edelmann 70404 to confirm clearance around belts, pulleys, and nearby components. Inspect related steering system parts and replace any damaged seals or fittings as needed during service.

Quality Assurance

Edelmann designs this pressure line assembly to meet or exceed OE specifications for fit and function. The hose construction is intended to support long-term steering-system reliability under normal operating conditions.
