The Schley Tools 13920 is a specialized 19mm 1/2-inch drive fuel line socket designed specifically for servicing Cummins ISB diesel engines. This precision-engineered tool addresses the challenges presented by high-pressure common rail fuel injection systems, where fuel line fittings are increasingly difficult to access with standard tools.

Key Features:

• 19mm 6-point socket design for secure grip on fuel line fittings
• 1/2-inch drive for use with standard ratchets and torque wrenches
• Engineered specifically for Cummins ISB engines and compatible with other Cummins engine models
• Allows proper torque application without adapters or complicated calculations
• Reduces risk of fuel leaks and prevents damage to fuel lines, fuel rails, and fittings
• Provides proper access to tight spaces around modern common rail fuel systems

This specialized socket eliminates the risk of rounding off fuel line nuts and enables technicians to correctly torque fuel injector line connections according to manufacturer specifications. Essential for professional diesel engine service and repair.
