Here's a trick re. siphoning that many of you may not know.

When transferring liquid from a container: Instead of sucking on the end of the siphon hose, if you can make a tight seal around the top of the "from" container, you can start your siphon by BLOWING into the top container. This saves you from getting a mouthful of, say, gasoline before you start your siphon.

I PREFER to use a safety siphon but this technique works well.

Any other tricks?

Depending on the situation but you can also insert the hose into the vessel, filling the hose with liquid.  Cap the opening with your thumb or plug and pull out enough to get that opening lower than the full vessel.  Uncap that low end and gravity should start your flow with no sucking involved.  I do it this way when draining my boat with it's built in tank.   It works for me because I have an excess of hose I can insert and pull out successfully bringing out gas to a lower level.

Nearly all cars have anti-siphon devices so you can no longer siphon gas from a car's gas tank.

Always, always,always use a clear see through hose when siphoning gas from a cars fuel tank to get fuel for your '73 Datsun!!!

Biggest 'trick' is get a SuperSiphon and not have to suck on anything.

My trick if I don't have a super siphon is to try to get my SO to suck on it first...

My experience has been the exact opposite. NONE of the cars or pickups in my extended family have "anti-siphon" devices or anything else that precludes the use of a siphon hose.

My sister's truck has such a device. I had to use a very skinny hose to defeat it. (I'm caretaking the truck in NM for when she visits. And my car is much more fuel-economical.)

Took a lot longer but hey... I made it to work that night.

I use one of those boat primer bulbs attached to a few feet of 3/8 fuel hose for my siphons. If it makes it easier a short bit of fuel line then a long section of steel brake line works well too.
