On a rib in a sea, where the primary fuel tanks are under your seat and the spare fuel is elsewhere? If i could install an instant replenishment system, ie as fuel is used it is replaced all the better. TIA.
How to transfer fuel cleanly?

Unless you devised & installed a pumped system the feeder tank would have to be higher than the tank to be replensihed, making it difficult if not impossible. Mr Funnel fuel filters are very effective in stopping particulate matter & water getting in...

Try 2ft of 3/4" hose slid on over the spout of your re-fill jerry jug . Insert hose in fuel filler first & then tip jerry can. Helps prevent spills.

Syphon from a full tank to a near empty one using a primer ‘bulb’ type rubber hand pump to start the syphon. Clearly if you can raise the feedeer tank a little that will help.

My son bought a refill pipe.One end is inserted in the full tank,other end is inserted in the empty tank.jiggle end that is in the full tank, and it starts the syphon off.One way valve is in the pipe at the full tank end. Buy them at most chandlers.

I use one of those plastic siphon pumps for diesel and another for bilge water. Very cheap but they seem to last for ever. The jiggle pumps look good but my plastic ones won't wear out so I cannot justify one. Often transfer fuel from a 15 litre bottle into the tank, sometimes at sea. They seem totally foolproof.

The idea of pouring fuel from one tank to another isn't going to work on a rib bouncing around at sea. If the second tank is a proper fuel tank fit either a second fuel line to the engine or a change over lever to switch between tanks.

I don't know if this is still the case but at the Southampton boat show there was a man selling a hose with a bell shaped fitting and a marble inside at one end of the hose. You jig the fitting in the diesel container and it's no spill no return filling whatever the weather. We used a funnel that removed water. While filling you can you can look in the container to see if there is any dirt at the bottom - which was endemic in the Caribbean. We used another one to transfer water from containers. They were the best pieces of kit on the boat after the wind vane.

That's a jiggle siphon, which can be had for cheap at Toolstation: http://www.toolstation.com/shop/p46767
+1 for second tank.
I, for my sins have occasion to sometimes operate a boat which is used for general purposes to do with Keelboat sail training. We always carry a full spare tank, and when the tank in use has gone down to about 1/4-full we pop off the petrol pipe and clip it on to the full tank. This ensures that, for one thing, any possible contamination at the bottom of the tank is not sucked up, and in the event that a refill has been forgotten about, (almost never happens
) there is at least a 1/4-tank of spare petrol in reserve. The proprietary clips on the tanks are proof against the entry of any contamination, or air, to the fuel feed and eliminate the possibility of any spillage on the deck, which could become dangerously slippery if 2-stroke mixture is involved.lw395

That is the sensible way to do it, but I think you will find the fuel is drawn from (near) the bottom of the tank so contamination is a risk. A filter in the fuel line is still a good idea.+1 for second tank.

But at the end of the day, you may still want to fill the built in tank from the portable tank?

We used to have 2 fuel tanks when racing to help with the balance fore and aft....with the fuel supply to the motor only coming from the larger aft tank. At certain planned times during a race, I would transfer an amount of fuel from front to back to maintain the balance, and towards the end of the race levae the transfer switch on for about 3 minutes just to empty the front tank and to make sure we had fuel delivery to the end of the race. A simple fuel pump on a switch and its really very easy. There was the odd time when the weather picked up during a race and we wished we hadnt transferred till later, or put more of the calculated race fuel in the front, but it worked a treat most of the time, and avoided picking up water ballast to keep the nose down, thereby making the boat heavier than it needed to be.

Thanks for potsing that URL, I would strongly recommend it as the easiest, cheapest and best way to transfer diesel and water, even if the boat is pitching and rolling as we found out over the Atlantic.
