Short inside fuel tank!?! Am I gonna burn up alive? 0_0

Hopefully someone has seen this before (and survived).

After having the RX-7 sitting on the carport since November I recently found out it wouldn't start. It turns over fine but never builds any fuel pressure (as in zero fuel pressure). Checked both fuel relays and they seem fine. Could not hear pump come on, even when jumpering F/P and GND in diagnostic box.

Well.... I was going through the service manual, testing continuity back at the fuel pump. Could not get continuity on the external pins for the connector that leads into the fuel tank. With the lid off and the pump out of the car I tested the pump and it had continuity across where the two pigtails connect after the come down from the "lid" where that connector with the pins is located. (sorry I don't have a clue what to call these)

Well I decided to unplug the pig tails from the connector on the inside of the lid and here is what I found (see pics):

I've also attached an image from the service manual showing what the photo's are of.

I need to replace the lid / connector for sure, but I'd *really* like to know what would cause something like this. I'm running a Supra fuel pump and have done the fuel pump rewire mod (fuse removed from inside block and new 20A fuse inserted into the block near the shock tower under hood). It's been that way (happily) for over 2 years. Only other wiring I had done was to add grounds as recommended in the fuel pump mod (Chuck Westbrook instructions).

Thanks for any ideas you might have!
