Gauge cluster needle calibration HELP!

[E30islifestyle]

I accidentally pushed the fuel gauge needle
Can someone tell me how to calibrate them to show me exact fuel in tank please?
By the way this is my first post and new user in here thanks!

Well, you could fill your tank, mark the position of the needle on the gauge, and that would tell you how far to move it.

Assuming your gauge works.

Welcome to the forum btw ;)

Thank you and for your support!
I did fill up the tank but I'm not sure in which place is exact full level on the gauge since I didn't mark it from the beginning...so now I don't have original position to mark:)
Oh well I guess there is no calibration..

What I mean is, now that it's full, mark where it points on the gauge. I assume you moved it counterclockwise. Then you can measure the distance between your mark and the full mark that is painted on the gauge. Then move the needle that distance clockwise.

If that doesn't make sense, can you post a pic of what the gauge looks like when the tank is full.

Use a picture of cluster that is not powered on to see the position of the fuel needle. Then relocated the needle to that position.
