Ok, so further investigation leads me to believe the fuel pump is bad or plugged up. I disconnected the line on top of the tank and attached my siphon line. I then hooked up the battery and turned the car on expecting to use the fuel pump to pump down the tank. Nothing came out. I tried with my siphon hose attached to each line and same result, no flow. Not particularly the safest operation, but if it was bad gas, using the fuel pump to pump the tank down would be the fastest fix.

I checked the fuel pump fuse (C4) fuse wasn't blown and that there is 12V there. There doesn't seem to be 12v across the plug on top of the tank though.

So either it is the fuel pump and I'm not reading the plug right, or maybe theres some relay in the circuit to control the fuel pump that I'm missing. My ancient 911 fuel pump pumps till the fuel rails are full then stops by itself.

So if there is anyone thats familiar with the fuel system I have a few questions:
1. What would prevent gas from pumping out of one of the three pips on top of the fuel tank?
2. Is there a relay somewhere between the fuse box and the pump?
3. What should I be seeing across the pins of the plug on top of the fuel tank.
4. Mostly importantly, how on earth do you get that ring off there to get the pump and level sender out?
