95 S14 fuel leak. Need help.

[cflslider]

So I've been reading various threads and hoping like hell this leak isn't a crack in the tank since it appears replacing the S14 tank is a nightmare.
Drip leak appears to have started within the last couple of days. Wife was using the car (first mistake,never to be repeated) and I just happened to notice the fuel smell.
Even on a incline, the fuel was leaking from the rear of the passengers side of the tank traveling to about mid way and then dripping. From the 'flow' that I could see, it was coming from around the strap area but that may not be the actual source.
I checked hoses at top of tank under trunk access cover and nothing appears to be leaking.
Car has about 1/4 to 1/8 tank of gas and runs fine.
Just so I could get a better view of things I tried to towel off the tank and realised that wouldn't work since it's probably under pressure so the leak would just keep getting things wet.
I prepared to de-pressurize sytem and took the fuel cap off. No leak !!
Assuming it's a cracked tank should that happen ? I would think if the leak were anywhere that fuel is it would still leak.
Anybody got an idea ?? I've never had to replace a tank on any car I've owned so I'm in uncharted waters here.
Where else should i be looking and how do I gain access ??
Thanks All. If there's another thread that I've missed, please feel free to give a link and I'll check it out.
