This is for carrying on a motorcycle.

It's flow rate is rather low of course, but when one needs to transfer a bit of fuel to a friend, then it's going to be invaluable.  

It takes way less space than a spare fuel container.  I drilled and inserted a small bit of wire into it, because who want's to have this fall off inside their fuel tank.  

The tubing is PVC tubing 6 x 1.5mm. the wire is .5mm inconel locking wire. (anything will do if it's small diameter)

I printed this from PETG .4mm nozzle.  One at a time because I want the maximum Z-bond so it doesn't fall appart.
