There is supposed to be a screen in the bottom of the tank on the fuel 
suction line. If you still have the FI gas tank, there will be 2 fittings on 
the bottom of the tank. The one on the drivers side is the suction. It is 
held in the bottom of the tank by a hex nut, and can be unscrewed.  This tube 
has a copper/brass screen on it, and if your tank has had water/dirt in it, 
it will be plugged. 
I just went through this on my '71 fastback. My tank was so dirty, that I 
ended up finding a different tank.
If you can, find a local radiator shop that will "boil out" your tank. There 
are kits that you can buy for the "do it yourself". POR15 people have one 
listed for about $50.
