Hi Giuseppe, here are closeup pictures of my bladder holder. I cut a rectangle of this material so that its circumference will be large enough so as not to constrict the inflated bladder. This is very important. Any constriction will cause false pressure and affect your engine performance badly.

I them fold it in half on a piece of paper and epoxy the edge. When the glue sets, I use scissors to cut the paper away, leaving the small strip that you see in the photo. I thread a zip tie through the mesh and lightly secure it to the medium sized fuel line where it connects to the filter. The filter has a plastic hook, that I secure to the fuselage with two more zip ties. The rear end of the mesh bag is secured with a string to the fuselage behind the wing. I usually position it so the paper strip is hidden from view.

It's positioned so the center of the full bladder is right on the C/G. Sometimes I put it under the wing out of sight. I fill the bladder from the end that connects to the needle valve. After you fill the bladder, let a small amount of fuel squirt back out to back wash the filter. After you fly, when you clean the plane, fill the bladder with alcohol and let it squirt out, and squeeze it as dry as you can. This will preserve the bladder so you can use it several times. I've used the same one for a month or more.
