When buying the stihl fuel tank assembly kit what other parts do I require?

I have just checked this for you and it all depends on what else you require. I have attached the Stihl schematic which shows what you will receive when you purchase the assembly. Please take a look and if there is anything else we can help with please let me know. https://www.lsengineers.co.uk/fuel-tank-assembly-for-stihl-ts410.html
