Well I accidentally drilled a hole into my fuel tank and need to replace it. I contacted Sig MFG and they said the fuel tanks were back ordered and they did not know when they would be getting a shipment of new tanks from China. The tank is a 8.8oz 260cc size. I have looked all over the internet and in 5 different hobby stores and cannot find this size\shape tank.

Please help me. It looks like most tanks come in even oz sizes. Should I get an 8 oz tank or a 10oz?

Any suggestions would be greatly appreciated
