This gas cap works perfect for my 14 gallon gas tank I bought for my 1923 t bucket from speedway. The gas cap that comes on the tank is a hard cap to get off and on. Bad cap that's come on it. . If you buy one of these aluminum tanks go ahead and get one, you will be glad you did. It's about $70.00, a little pricey but works a whole lot better. Very satisfied with it.

Very nice
