20503566 Bleeder Screw | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta bleeder screw is an OEM service component used in the Fuel-Tank Bleed Point. It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta TB-series fuel-tank installations application. Technical identification: Bleeder screw/plug for the fuel-tank mounting and bleed point; Volvo Group product group 2540, function group 1515. In service, it opens a controlled bleed passage so trapped air, vapour or residual pressure can be released from the connected fuel-tank or fluid circuit, then reseals the port during normal operation. Selection must be confirmed by OEM part number 20503566, the exact model/product number, serial number and installed assembly configuration.

⚙️ Key Features

• Genuine Volvo Penta OEM bleeder screw
• OEM part number 20503566
• Technical distinction: Bleeder screw/plug for the fuel-tank mounting and bleed point; Volvo Group product group 2540, function group 1515

🔌 Function

Opens a controlled bleed passage so trapped air, vapour or residual pressure can be released from the connected fuel-tank or fluid circuit, then reseals the port during normal operation. Confirm dimensions, thread and strength class, inspect mating threads/contact faces and tighten to the Volvo Penta torque and locking specification.

⚠️ Common Signs of Failure

• Fuel or fluid seepage around the screw and seat
• Air repeatedly entering the circuit after bleeding
• Blocked bleed passage preventing trapped air or pressure from escaping
• Damaged threads or head preventing correct tightening
• Hardened or damaged sealing face causing repeat leakage

🛠️ Service Notes

• Open the screw only enough to release trapped air or vapour, then retighten before returning the tank or circuit to normal pressure
• Do not run the engine or pressurise the circuit with the bleeder screw open
• Tighten to the torque specified for this fitting; overtightening can damage the sealing face and cause the leakage it is meant to prevent
• If fuel weeps after retightening, check the sealing face for damage before assuming the screw itself has failed
