Certianly can. Use 3 clip leads. One from battery neg to one terminal on the gauge. One from the other terminal to the sender teminal. The last from the sender flange to battery pos. Move the float and observe the gauge action. These systems do not react quickly so allow a 10 to 15 seconds for a reaction.
