It will start leaking from around the cap. I know this because I occasionally used the soda bottles for spare fuel. If it has fuel in it for too long the seal inside the plastic cap will start to deteriorate and gas will leak out.considering theres no fuel pump and its all gravity an upside down 2 liter pop bottle would work...lol just make a hose from the cap part to the carb
Dude -- a soda bottle will Disappear on contact with petroleum if it is not #2 HDPE (High Density Poly-Ethylene). If a plastic container is Not HDPE it will melt in your hands the instant petrol touches it.considering theres no fuel pump and its all gravity an upside down 2 liter pop bottle would work...lol just make a hose from the cap part to the carb
