Lost Gas Cap

Bruce0710

I have a 350 Express Cruiser and yesterday while refueling the chain on the cap broke and the cap went into the water. Unretrievable,so does anyone know where good replacements are availavable. They aren’t as common as you’d think.

The on the Rinker is a screw on 3 1/2 inch to fit 2 inch nozzle opening. Most of the one out there on Amazon, West Marine etc are 1 1/2 and aren’t simple screw on replacement . Anyone else have any idea ?

This is a screw on and the threads on this cap are approximately 1 7/8" O.D. for a 1 1/2" fill opening. 

They only make one of this style so I'm not sure what else it could be.
