3862109 Cap | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta cap from the Marine Propulsion group, weighing 20 grams and listed for 85 applications on the XDP series. It supersedes 3862175, which was catalogued earlier as a reservoir — so the old number covered a larger assembly than this cap.
