20363743 Pressure Pipe | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Pressure Pipe - Part Number: 20363743

This genuine Volvo Penta pressure pipe is a rigid formed high-pressure injection pipe calibrated for one specific pump-to-injector position used in the mechanical injection high-pressure delivery line, schematic position 12. It is manufactured to the original Volvo Penta dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it carries precisely timed high-pressure fuel from the injection pump to its assigned injector without pressure loss or pulse distortion. Selection must be confirmed by OEM part number 20363743, the exact engine or product model, serial number and installed configuration.
