GM 89060639 LB7 Duramax Fuel Sending Unit 2001-2004

The fuel sending unit reports fuel level readings to the instrument cluster. If your experiencing erratic fuel level readings or an inoperative fuel gauge, there is a chance this is the issue. This is an OE replacement, so accuracy and fitment will never be an issue unlike with cheap aftermarkets.

Note: New sending unit includes rubber sealing ring.
