Chainsaw Repair

Hey guys, thanks for the previous help. I fixed the oil pump and now getting oil to the chain. Never thought id need to take it all apart however it was easy enough.

Now im looking for the proper size of fuel line. The local small engine place gave me some green coloured lines that look the same but is obviously too small. I am stretching the crap out of the lines to fit over the connections and they also don't seal when i put them through the tank.

What type of line would be best and what size would i need?

I'll check mine in the AM.
