Syphoning

If you can fill the tube somehow (funnel, tip diesel in?) with the end you suck higher than the other end, you can quickly drop the 'suck end low and it'll syphon.

In the same way, to siphon a bath with a hose, attach the hose to the outside tap, with it running in the window into tha bath, unhook the tap end downstairs (you'll get wet!), and the water will drain

Aquarium shops and also CPC sell small plastic syphon pumps for a few pounds--£3 IIRC.

Push all the pipe down into the tank, put thumb over end, and pull out tube. Tube will now be full of diesel. You can now drop end with thumb below level of tank, remove thumb and you should have a syphon.

That only works if you hand is thin enough to fit down the filler pipe (or you have a lot of spare pipe, and it is flexible enough, so that you can push under the liquid, and so fill, more than twice the length from the surface of the fuel to the top of the filler pipe).

I'm sure I've seen a device somewhere with a little piston inside the tube on the end of a piece of string which passes through the tube. You feed the piston end of the tube into the liquid, pull it out the other end with the string, and the liquid follows it.

That's it, brilliant idea, just love the simplicity of it, must make one.

a small piece of sponge on a piece of welding rod could do this in the workshop i simply blow the airline across the end of the syphon pipe which causes vacuum

Oi Mate ..... I think you may have just invented the carburettor!

No special pistons needed, 4' plastic pipe, bit of string with a piece of cloth tied to the end, the water just follows it up the tube!

Cheers "Set Square" sometimes the simplist of ideas are the best!

No more burping Diesel or Petrol for days on end!

Someone patent it, fast, before microsoft do!

The first two bits of advice are even more relevant to siphoning petrol!

Try a yacht chandlers.

Use transparent tube?

You can get 12v pumps that come on the end of a tube - the pump end has a little filter and is small enough to drop down into the tank. You then simply pump the diesel out. Maybe a bit overkill when syphoning will do the trick - but if its something you do often then it would certainly be worth it.

Having filled a diesel van with petrol recently I found the easiest method was to use the tube and bulb used to start an outboard engine from a portable fuel tank. You can keep squeezing which is quicker or just leave it to syphon.

Cheap and cheerful - substitute a tampon (Tampax) for the little piston, and just tie a longer piece of string to the string already provided. Thread through a few feet of garden hose. Job done. Done it loads of times :-)
