You may be surprised at how important a secure connection and especially a good ground really are.

Certain things (like MSD boxes) are especially sensative and won't work right with an improper ground. Older fuel gauges (60's and 70's, maybe even later) will shoot up to way past full with an improper ground, and if it is a loose connection the gauge will be all over the place. I'm not sure if this is the case in your car, but it is worth a look.

Did your mechanic install a new sender? Do you know what the resistance of it is vs. the range for your gauge?
