Chrome Plated Deck Fuel Fill Replacement Cap Only SeaDog Line

The chain on my last one broke so I ordered this and it fit with no issues.

My mistake i thought my cap was a inch and a half diameter, its a little bigger, the o ring on the new cap worked on my old one,as i was having a hard time finding a proper fitting o ring,so it still took care of my problem! Thank You! Steve Vlachos
