Are you talking about the black plastic screw on vent caps? I have a 92 Sabre and mine have “Perko” on them. If that is what you are talking about, I had to buy one for my boat because I lost one. I had to order the whole gas vent assembly because I could not find just the caps. It wasnt very expensive and I figured if I ever need the vent for anything, Ill have it. You may have better luck.Jim EbarbMany, LA (Toledo Bend Lake)2004 Cougar/ 225 OptimaxHumminbird Helix 12 Chirp SI on BalzOut Mount at bowLowrance HDS 7 at bowHumminbird Helix 12 Mega SI on Ram Mount at ConsoleLowrance HDS 8 in dash at console
