All of the factory installed sending units I've seen were screwed in at the top of the block, rear rail, behind the intake manifold. If that is the style in question, there is probably a special socket made for the purpose, but a pair of channel lock pliers or vise-grips can be used to unscrew the sender and install the new one. Since the threads provide the ground connection, teflon tape or other sealant could prevent getting a good ground.
