I was filling up yesterday and even though I knew better, I didn't have the fuel fill cap in my hand as I pulled the nozzel out of the fill and it cut the chain. Of course it went strait to the bottom. I need a replacement, but I recall buying one at West Marine that was just slightly too large and wouldn't seat/seal. It might have been a Perko. Here are the relavent part numbers 1 1184746 DECK PLATE, DSL SS 2"W/1.5"OUTLET GRN CLR-COD 1437557 DECK PLATE, GAS CAP W/CHAIN I think the cross refernce is a Attwood. is this the right part??? There are a couple options.
