Entirely molded from Fiberglass Filled Nylon and do not require grounding to the boat electrical system as required on all deck fills using metal components. Each deck fill has a special cap with a built-in key for easy cap removal. The hinged key can be locked in the upright position to open or close the fill and then recessed into the cap for a flush surface.

In addition the caps are molded in special colors to help prevent the dangerous and costly problems caused by placing fuel in water or waste tanks or vice-versa. The cap threads are 1 1/4” - 111/2 NPSM - Straight. Gas, diesel and water caps include attachment chains.

NOTE: Will not work with pressurized oil injection systems. Connect deck fill to reservoir via hose (not included).
