01 volvo s40 113,000
recently replaced my fuel pump with a used fuel pump from same model with 64,000 miles. Now the fuel gauge doesn't work and i was wondering if mabye something has to be reset or if the sender unit on this one is just bad.

 

Sender is bad or something as long as wiring is different.

 

yea swapped fuel pump itself from new assembly to old assembly works fine thanks

 

Glad it is working now.
