Technical Fuel gauge issues

[savage00]

Hello , I have the Bravo 2007 1.4T-Jet 2007.I've been having fuel gauge issues, so when i fill up fuel the arrow goes up, but after i drive for a while it goes down pretty quickly and if i have low fuel it's like i don't have any , the arrow is all the way to the bottom. So i've ran out of fuel a few times on the road because the gauge does not show to my actual amount of fuel and the km range is showing pretty random numbers. I pretty much never know how much fuel i actually have, also when i fill up like low amounts it either moves like 1 or 2 lines or it just stays on the lowest point it's like the car is turned off. I've tried changing the whole fuel pump+gauge but it didn't fix it , sorry for my awful explanation

Sounds like it might be an issue with the float getting stuck maybe, do you get any ODB2 error codes?
