Hello,
I recently changed the fuel pump on a 2002 Mini Cooper S R50 I believe . Although the pump works fine, the gauge won't go below the one quarter mark. When I partially remove the pump from the tank and manually move the arm, the gauge does move through its full deflection. Could there be an issue with the sender unit, or did I install something wrong ?
Thank you

The sender may be jammed in the tank. Check if the fuel pump is orientated correctly.
