BB I feel your pain, I fueled up my boat one time just after a fuel tank repair and found it to be still leaking, anyway to fix it I had to drain the fuel tank. I had to syphon the fuel out of the tank, I used a length of garden hose to siphon the fuel. Started the syphon and it stopped, blew back through the hose to clear the fuel out of the line but obviously not enough because next thing I started sucking on the hose again and copped a large mouthful of 2 stroke mix. I have no idea on how much I swallowed but I know it was a fair bit, I had fuel flavoured burps for 2 days. The ER doctor was very specific in telling me to not smoke for at least 2 days, I had to tell him about 4 times for him to understand enough english to realise I'm a non-smoker.
