Fuel level, NAC but VAC

[Tihol Tiholov]

Patient '92 Eurovan.
Fuel gauge was not moving.  Fixed it with re-soldering a chip-like voltage
regulator on the instrument cluster.  Then fuel pump gave out, pulled it out
- it's a unit along with the fuel level sender.  Reinstalled and the fuel
gauge moves no more.  Dug into it again - the floater moves up and down,
fuel pump works, gauge refuses to budge.  Any ideas, BTDT's?  Fuel tank is
almost full to make matters worse.
Thanks,
