I'm going to suggest a pin hole in the fuel line or damaged o-ring in the fuel line connector. Holds true when not under pressure but as soon as it's operating, the leak is happening. But to inspect it operating, it's got to be installed and therefore not seen, so the inspection hole is the best bet so you can get eye balls on it and finally see what is happening.
If you believe it to be getting squashed, a borescope up in the top would confirm it. I don't see how it could be getting squashed. It's not going to be going in any different to when it was made, unless it is pressurising, to which the EVAP canister might be rooted or the purge no good, or the new fuel cap faulty, but its clearly happening around the pump and not elsewhere. If it was bulging, it would happen elsewhere on the tank I'd think.
