Gas guage problems..

I think you mis-understood my post. For less than $10 in parts from Radio Shack you can add enough hysteresis (electronic damping) to the sender signal that the gauge doesn't jump around with the cheap senders.

Here's a link to some discussion on an electronics board about building a simple anti-slosh circuit for a 1960's Italian car. http://www.discovercircuits.com/ubbt...er=6590&page=1

I would guess GM used mechanical damping on the actual movement of the sender arm. F*&d used a simple circuit on the gauge panel with cheaper senders.
