Gas gauge doesn't work???

[Car Nut]

My stock gas gauge hasn't worked in a couple years or more. I just had a FRPP fuel pump assembly installed (literally the whole assembly was replaced) and that didn't fix the problem. (Needed a new fuel pump anyways)

I remember reading a long long while back that another possibility to a non- or rarely working gas gauge could be a fuse.

Anyone know where the gas gauge fuse might be?

Any other ideas?

Thanks!
