Chrysler LHS Fuel Level Sensor Issues
Chrysler LHS Problem

My car has this problem. Everything works fine except the gas gauge reads empty and the gas pump light stays lit. I use the resetable trip odometer to keep track of gas used and reset it on each fill up. But what I would like to know is can you purchase the level sensor by itself without having to buy the entire fuel pump module?

Fuel guage reads normally with full gas tank but will go to empty after about 50 miles of driving.

Fuel gauge indicates full when tank refilled but goes to empty after 50 miles and remains on empty until refill.
