Ted Tine Performance Products is the first in the industry to manufacture a fuel valve with an innovative "click." Our patented fuel valve is specifically designed to indicate positively where 'on,' 'reserve' and 'off' are. Finally you never have to worry about where reserve is! While other in the industry constantly change and increase their flow using the original design of their valve, ours always has been 88 ounces per minute. The confidence we have in our product design allows us to continue to provide a lifetime warranty that you can't find anywhere else.
