I have a 2000 310 DA with an 8' inflatable tender and a 3.5 hp ob with an internal tank. How do folks here carry gas for their tender? I do not like the idea of carrying a gas can on the boat. I was thinking about a siphon pump to draw fuel from the main tank as needed. Thanks.
 
We store extra fuel tank in the Dink while dink Secured on the davit. Keep it draw latched inside the dink. The siphon trick has its draw backs. Us old guys may have had to learn this lesson a few times.
 
a newer gas can will leak less than trying to siphon fuel from your main tanks.
 
Boston, I guess we should have first asked what was your concern with carrying a gas can on the boat. The plastic ones seal tight, won't scratch your floor if they slide around, and you can get caps to plug the outlets so they don't stink.
 
Very helpful, thanks. My concerns around a portable tank is how to secure it in the cockpit and if it did leak, the risk of gas in the bilge.
 
I kept mine on the swim platform secured with elastic cords. I used to keep the outboard out there as well.
 
Since the spare fuel was always meant to be used by dinghy, I kept it in the dinghy. On my 8'6 tender I had special under-seat storage where I kept few things, including the spare gas.

My new AB tender has few compartments to choose from for storing spare gas. In both cases I'm using older gas can and it works fine, no leaks.
 
Different boat but I keep a 3 gallon can in the back corner of our dancer - slides nicely into a pocket there.
Siphoning probably cannot be done because of anti-siphon valves in the tank, I know on our 270 it can't for that reason.

As Gofirstclass said you can get caps with plugs so the spout is not sticking up.
I use a 3 gallon can with the caps and a spout that sets down in the can when not in use. Keep it simple.
Something like this would be stable and not leak:

These newer, no evaporation "green" cans suck. Auto closing, levers, nozzles of brittle plastic. I have yet to find one of these that will not start leaking.
I have spilled more gas trying to fill up snow machines and ATV's with these type than would evaporate in a lifetime.

Sample Leaking type to avoid - NO GOOD:

For ventless cans, do you all not worry about it sitting out in the sun and pressurizing (with potential to spring a leak and spray)? I am curious about the answers on this thread, but my new dinghy (as of Wednesday) is a jet ski. So I'd need a bit more gas than the usual dinghies.

This is without a doubt the best gas can I've ever owned! I carried this on a landscaping trailer all over the southeast in full sun and never had a problem. I sold both company's years ago and still have one for personal use and it's probably 10 years old.
