Need help finding correct fuel cap o-ring

[dgreen1069]

I have a 2000 Marlin 300 and I need to replace the fuel cap o-rings. Can anyone tell me what model fuel caps are used on our boats. If nobody knows the cap model, can someone tell me what size o-ring I need. I am not near my boat right now or I would just take the cap with me. I have a West Marine around the corner from where I am and I'd like to buy the O-rings if I can.

I took my old O-ring to an auto parts store and they matched it up.
If you don't have the old ring measure across and they still should be able to match it up.
Auto parts stores have an assortment of these.

Sorry but in my hast to answer I didn't read that you was away from your boat.
You may just want to buy an assortment pack because they are not that expensive.

I'm away form mine, but search the last couple of months. Someone asked about them for the Sailfish, and I can't see them being any different. Or call Grady. 252.830.8600 I have that in my phone cause every time I call they are nothing but helpful!
