Edelmann 70640 Power Steering Cylinder Line Hose Assembly - Cylinder

Edelmann 70640 Pressure Line Assembly

The Edelmann 70640 pressure line assembly is built for steering systems that need an OE-style power steering hose with accurate routing and a precise fit. With a 10.375-inch hose length, it is designed for direct replacement service on select Mercury and Ford applications, including Mercury Monarch, Mercury Montego, Ford Mustang, Mercury Cougar, Mercury Capri, and Mercury Villager.

Edelmann Pressure Line Assembly products focus on matching original hose geometry and construction details so the line follows the factory path through the available space. This helps maintain proper steering system routing on vehicles such as the 1967-1970 Ford Mustang and 1968-1970 Mercury Cougar.

This part cross-references Gates 353300 for the same application.

What It Helps Fix

• Leaking or cracked power steering pressure hose
• Hard steering caused by pressure loss in the line
• Routing issues from a damaged or incorrect replacement hose
• Noise or contamination related to hose deterioration
• Fitment problems on OE-style steering cylinder line applications

Installation Notes and Tips

• Verify vehicle year, make, model, and cylinder-position fitment before installation.
• Inspect the steering cylinder, fittings, and adjacent lines for wear or damage before replacing the hose.
• Confirm the hose routing matches the original path to avoid contact with moving or hot components.
• For 1976 Mercury Monarch applications, note the OEM design and flared fitting requirement listed in fitment notes.
