Many intermittent connections at or on the instrument cluster can be temporarily made to work again by a medium fist 'thump' on top of the dash panel. The mechanical jarring will sometimes 'fix' the bad connection.
Certainly while the cluster is out, gently spread the terminals. A drop of Deoxit and plugging them on and off a few times should scrub the contact surfaces clean. Solder joints and the gauge-to-board terminals can be sprung for firmer contact and Deoxit applied to those contacts as well.
Bad solder joints usually happen at the larger through-hole leads and the fracture may appear as a dark ring around where the lead protrudes from the solder. Touch up any joints that look suspicious.
P1681 is a powertrain fault code (PCI bus) that is between the PCM and cluster. The fuel level signal is sent to the PCM for OBDII reasons. I imagine that a bad connection could occur anywhere in the bus path.
