Refer to Sneeker post.

Or you could do this and still use modern bladder material. Paper towel roll. This one was built for me by Larry Davis many moons ago.

Robert there are a LOT of options
Red Caps
Pipette Bulbs
Gerber pacifiers from Wall World
Pen bladders are still specialty items to be found
Fuel tubing bladders from Texas timers or Phil Cartier
My experience is the store bought Gerber pacifiers are 1. expensive and 2. very high pressure
Red caps are about perfect but deteriorate fast
Scientific Pipettes are nearing the best of both worlds but I do not seem to be able to train one to be nice and round
For my casual every now and then fun flight the red caps work for me....real combat competition needs a more reliable and repeatable method and the various fuel tube bladders seem best
Ball or sausage can humped bladder compartment is best with red cap, pacifier, or pipette... tubing bladders need a rocket tube type compartment

Phil Carter to the white courtesy phone. Phil makes them.

Not sure what I can add here. Pipette bulbs, usually 2 mlj , used to work fine. The shorter you tie it the rounder it will blow up, but the less fuel it can hold. It's easy to tell when you've overfilled it. It bursts.
Pacifiers are better on older engines. They have much lower pressure which makes the needle valve easier to set. Pacifiers were around 6 psi. 1/4 x 1/16 wall bladder tubing is around 20 psi. 1/32 wall is in between but doesn't last very long.

I have bought some pacifiers from Bob Mears on eBay that work really well. Tim

https://www.ebay.com/itm/172216355832 here are your pacifier solutions. But your voodoo has a long tube for a regular tube type bladder. This guy will have everything you need http://www.mbsmodelsupply.com/index.php

Back in the 90s when I was running Phil’s yellow jacket tubing bladders I made the compartment space out of a plastic tube that was recommended to me by one of the New England crew. It was made from a golf club protector tube. Just cut to length and put ends on it.
I understand fluorescent bulb protective tubes work also, available at HD and/or Lowe’s. They have the additional advantage of being clear.
I’ve never run anything but yellow jacket bladders so I can’t comment on pacifiers and such, but I found them to be reliable and easy to work with.
