Thanks to all the responses so far. I definately have only two lines coming out of my fuel pump: supply and vent (the vent line runs back into the filler neck right under the fuel cap). I must have the "newer" returnless style fuel injection sytem.
As I mentioned, there is a blocked "port" at the very bottom of the fuel filler neck right before it goes into the tank. I tried to suction some fuel out of this port but couldn't get any. This is hopefully due to me running the tank almost empty in preparation for having to drop the tank. I am going to fill the tank to half full and see if fuel can be drawn from that port.
If anyone had been down this road, please let me know.
Thanks!
