Best Use Case
Use this cap to replace a missing or damaged cap on a Sea-Dog 351750 series deck fill. The tether chain prevents the cap from being set aside and lost during fuelling or filling. A missing deck fill cap is a safety issue — replacing it promptly keeps water and debris out of the fill hose.
