The best gas cans you can get are made of steel… I do not think you can source the old jerry cans, maybe you can, what you can source these days are the steel NATO cans and the steel nozzle. Gas stored in steel cans does not let the lighter ends evaporate off. I loved the old steel jerry cans, super safe to carry fuel with.
But, as
@h2oskierfl95 stated, I have the VP gas cans, very strong, super simple, and they don’t leak. If they leak on you, you are doing something wrong. For how I use them I can leave the dispensing hose on, but if you get yourself extra caps you can just have the one dispensing hose / cap for all of your cans, and when you are storing or transporting the cans just have the cap on without the dispensing hose, makes for a lot lower profile. For fueling on the water, you can just get a longer piece of pvc hose to make a long fueling hose from the vp can so you can stand up and back from the fill cap on the boat.
The thing with filling fuel cans in the back of a truck is that the truck is sitting on rubber tires and will be at a different potential from the pump / fill spout and the ground. By putting the cans on the ground, the cans are then at the same potential as the fill spout, this greatly eliminates the risk of a spark. Its the same with your car’s gas tank.. so the logic does’t hold to me for putting cans on the ground. If you have your hand on the metal of the pump fill spout and touch your car or cans first before getting the spout near to the tank or cans you will greatly reduce the chance of a spark as you become the conductor to ground your car/cans to the pump handle / spout. I just touch the fill spout to the side of the cans first to put them at the same potential, and, this is where things can go awry, keep the metal fill spout in constant contact with the plastic or metal gas can at all times during the fuel process, this keeps static electricity from building up between the two.
When they fuel aircraft the first thing that happens is a ground wire is connected to the aircraft and to the tie down hook or dedicated ground point before the fuel hose is ever pulled off of the truck, or in the case of hydrant style fuel systems the pump bogie.
