Gasoline guage jumps.

Ever since I had a fuel pump installed, every time I speed, go up/down a hill or brake hard, the gasoline guage on the dash shows different reading.

It would go to almost full tank , when there is only a 1/4 of gas in it. I never had this issue with old fuel pump.

What I need to know is WHY this is happening. If it is improper pump installation or tuning, I NEED to go back to the mechanic who ripped me on 700 dollars to install it.


THANK YOU

Take it back to the mechanic. It sounds like he screwed up the fuel pump installation and damaged the fuel level float and sending unit which is part of the fuel pump pod or installed the wrong one. See pic below:
