Brand new, Perko filler neck spacer. The Perko 0540DPRBLK black plastic mounting ring should be used to lift the height of the deck filler in any application where water might be splashed around a vented filler. The ring raises the opening between the fuel cap and fill and additional 9.5mm (3/8") above the deck surface thereby reducing the likelihood that splashed water will enter the fuel system through the deck filler breathing vent. Sold each.
