is there an easy simple way to calibrate fuel gauge

[Aldog3788]

i recently did gauge over lays but it i had to remove the needle for gas
every other needle is fine i jus wanna know how much gas i have

Hmm I not sure but my best guesse would be. Fill ur car right up. then you know where it should be. Rite?

yea but i tried that i heard theres a screw behind the neeedle to move it up and down but i dint see one
the needle can only turn limited amount of times
