For Mercedes-Benz 190E, 300E, 300CE, 300SE, 300SEL, 260E, and related models, this connector is listed for air flow meter boot to idling adjuster locations. Other applications include the connector between the idle speed actuator hose and intake manifold hose on select 300SL and 300CE models, plus air flow meter boot and fuel distribution line hose locations on certain 420SEL applications.

Common Issues This Part Can Address

• Cracked or leaking hose connection at the air flow meter boot
• Loose fit at the idle speed actuator hose connection
• Damaged connector between intake manifold hose sections
• Fuel or air leakage at a worn connector point
• Restoration needs on older Mercedes-Benz fuel and intake plumbing

Installation Notes

Verify the exact vehicle, year, and hose location against the fitment notes before installation. On many Mercedes-Benz applications, this connector is used in a specific position within the intake or fuel routing path, so matching the original routing is important. Inspect adjoining hoses and boots for wear, since a new connector will not correct damaged surrounding components.
