Don't do that! The reserve level threshold is adjustable on the sender. It can determine when the lower wiper contacts the plate.

In the photo above, you can see a toothed wheel.  This wheel rotates on a nylon pivot, causing the bottom plate to be rotated and the contact to change position.  Using a small screwdriver, get a purchase on either of the indicated lever points and engage the tip of the screwdriver's blade with one of the teeth of the wheel.  Rotate the wheel with a levering action. 

• Rotating the wheel CLOCKWISE will cause the wiper to contact earlier, resulting in a LARGER reserve volume.
• Rotating the wheel COUNTERCLOCKWISE will cause the wiper to contact later, resulting in a SMALLER reserve volume.
