I could be wrong about this, but I was under the impression that a fuel cell is a "bladder" with "foam" inside that goes inside a "metal box". I don't know that the metal box holding the bladder is necessarily meant to hold the fuel in. I thought the bladder holds the fuel in.

So I am guessing that when you replace the "fuel cell", you are replacing both the bladder and foam?

So if you only replace or simply remove the "foam", could it be that the "bladder" is still the part that is leaking, which would not solve your problem if the metal box containing the bladder is not necessarily meant to hold the fuel in?

I think the "foam" acts to prevent the fuel from sloshing around the tank, so I think the idea of getting a baffled tank is that the baffles prevent the fuel from sloshing around the tank, which might be why some CSX4000 owners replace their setup with an aluminum baffled tank. If you do not take your car out on the track then the baffled tank might not matter.

It seems to me that Craig's customers give him nothing but glowing reviews of his work. I think Nick seems to have mixed reviews of his work.
