Absolutely most handy tool in my tool box

I can only guess at this time that it starts a siphon without the old fashioned method of lip suction.           I'll have to pass on this one too.

Question - If the jerrycan is sitting on the ground is this siphon strong enough to transfer the water uphill into the trailer/camper?

I currently have (15 years now) and use a drill-powered fresh water transfer pump.  It transfers 6.5 gallons in seconds.

It will not siphon uphill.  Like any siphon, it needs to be lower than liquid being siphoned.   I used it with a 7 gal water container shown here  when my back went out and I could not lift it.   I use it all the time to empty a 55 gal drum of water into my cabin cistern in about 10 minutes. when I draw water out of the stream, I find a place that is at least level with the water and have no problems pulling it.   I have also used it to siphon gasoline from my truck to a container for my lawn mower.  

How it works is simply a marble crimped into the copper tubing that you when you move down it lets water in and blocks water escaping when you pull it up.    In my 7 gal it takes about 8 to 10 of these up/down movements to pump enough into the hose to get the siphon started.

Thank you for the answer Dan.  That won't work for us, but glad that it does for you.  

I agree this is a great tool. I've used it for years.Never taste gas again.😅

As a kid I had to set siphon tubes into ditches to irrigate crops.  You place your hand over the end of the tube to pull the water up and then just plop it down over the ditch bank.  That skill has stayed with me over the years and anytime I need to start to siphon I just put my thumb over the end of the tube to create a vacuum.  Same idea as the marble but on the other end of the hose!

I think the one I bought at Harbor Freight was labeled "jiggle pump".

The newer cars and trucks have screens in them to prevent a siphon tube from stealing your fuel. Yea!

Of course this is a problem if you inadvertently fill you diesel tank with gasoline.  Or so I suppose....

Just purchased one and have already used it.
