A Perfect fit for my McCulloch leaf blower/vac gas tank! The two of them both were OEM quality and condition was mint. These will probably outlast the blower they were purchased for but the value is well worth the price. Just in case I misplace the dilution ratio for gas to oil mixture I now have 2 caps that both have the 40:1 ratio printed right on top so the new appearance is perfect! Have to go back to this sellers site and see what else I can get!
