Kaya po ba ninyo calibrate/ayusin fuel dial ng Honda City 2004 1.5VTEC?

This car was a victim of Ondoy. Because of the extremely long queues of Honda Casa I got it rehabilitated by freelancers. ECU, engine, etc. ok naman lahat except for the gauge panel board which was replaced. Problem is the fuel dial defaults to 50% full kahit almost empty.

Can you guys calibrate and fix this? I'll be picking the car next sunday and if you can handle it bring it to speedyfix. Thanks.
