Need some help with Fuel Level Sensor
 

Hello Errybody,
I'm new Obviously, But iv been lurking for few months.
I never felt like I needed to join because I got all the answers I looked for.
Except for now,
I have a 87 Fairlady. Fuel level wasn't working so I got a new one. Duh
Installed it with no problem. But its still not showing I have a full tank. It shows 1/4 or less of a tank. The part I got was of new design which I read was common. But WTF? Am i missing somthing.
Thanks in advances. :armata_PDT_37:
