The simple test is to eliminate the speedooooo
1 disconnect the speedo and the tach.
2 connect the tach cable to speedo and the speedo cable to the
tach-oh-meter.
3 drive the car. if the speedo still jerks around it's the guage.
if the tacho jumps around it's the cable.
4 then fix the problem.

To eliminate the sending unit get a "aligator clip" jumper from someone like
radio shack. at the sending unit (top of the tank) connect the green wire to
the black wire. with the ignition on the guage should read full. If it
doesn't then either the sending unit is bad or the float isn't floating. If
the car has sat a long time rust could attack either of these parts and make
them function incorrectly.
Good luck and Aloha
