Ken as I understand it Binky are no longer...same basic shape is the Walmart Gerber non othro versions...real PITA to get the hand ring out of with my old hands. They are about $2.59 for a two pack, so from posts here, they sound fairly expensive

Compared to bladder materiel like we use for the Big Block. I think they have a lot more pressure..... I tested a Gerber against a two inch length of bladder through same length fuel line and the Gerber 2.5 oz went about 2 foot longer faster stream on my driveway

I buy Binky's at CVS. They work great and are quite a bit softer than the ones from walmart. Hard to get apart though. The red caps work awesome, cheaper and easier to pump up but not as much pressure.

thanks guys.
The red caps that I tried were sub standard (imho) so I'll try the wally world thingy.  There really is no problem using bladder tube but the Blitz just looks cooler with the hump..."what hump?"

Amazon sells Gerber Soft Center pacifiers, a 6 pack is $12.85. Texas Timers (a free-flight site) sells step-down pressure fittings to make needling a little better:

Texas Timers even sells the old low pressure black pen bladder tubing, too.

  For me on my 36x bb, the pipette bulbs did not supplied enough of fuel (40 nitro) and it cost me to lose a engine. I use the Gerber soft center pacifiers. To take them apart, put the plastic shield in a vise and warm it up a little with a heat gun. Then with a big screwdriver pry out the ring from the shield, it will come out pretty easy.
