I have a JD 21HC hedge trimmer that I need a fuel tank assembly for. John Deere does not carry parts for this model any more. They suggested that I find an echo dealer for parts. I have searched online and the closest trimmer I can find in Echo to the JD is a HC-230. The only thing is that the tank on the Echo mounts with the screws from the side and the JD screws come up from the bottom. I have had this trimmer for about 10 yrs, and don't want to throw it away. Runs and cuts great but just needs a gas tank assembly. Any Ideas?
