Fuel Tank "air bladder"

I have a question that may not be VW air-cooled specific but I know some of you guys here might know about.

I am working on a Porsche 924 and today I sealed the fuel tank with POR Fuel Tank sealer. Anyway, prior to sealing the tank I connected the air compressor and blew air into the tank to blow out the dust and I accidentally blew air into the air bladder and it popped.

The question is:
Am I ok to still use the tank with this component out of commission? Is this technology out dated? I don't see newer tanks with this in it.

What is an air bladder?

Is that like a collapsible fuel tank?

Is this car to be used for racing?

If it is a collapsible fuel tank, I think it would help if you were in
an accident or if someone fired bullets at your car and hit the gas
tank.
It would be less likely to catch on fire.

But for everyday use, I think it would be as safe as a stock classic
Beetle fuel tank.

Its some sort of rubber diaphram attached to the inside ceiling of the
stock metal fuel tank with a line running to it from the outside of
the tank. The line is either feeding vapor or plain old air into this
rubber pouch.

The car is not used for racing. Its a stock 1979 Porsche 924 with a
watercooled VW engine in it.

I posted this question to alt.autos.porsche
We'll see.

I doubt I will get an answer since most of the porsche newsgroups are dead
and full of trust fund babies wanting advice on buying **** they know
nothing about.

Thanks everyone.
Maybe someone will see this here and know something about this oddity.
