Just recently had my fuel pump changed along with some type of switch under the dash board. Now that damn fuel gauge is stuck at 1/4 of a tank even after I fill the car up. I have taken it back to the shop that replaced the fuel pump & it's still the same damn thing. Any insight would be appreciated.

My car is a 95ZA4 that's basically stock with a K&N & a Flowmaster.
