2001 f250, no tail lights

Hello all, I rarely use my truck at night except when I snow plow, well low and behold I may have to plow tomorrow morning. Everything seems to be working except the tail lights. The bulbs looks fine. I have looked and looked to find where the fuse is for the tail lights and I cannot find it on any sight, all people say is "check the fuse box". Well, nothing is labeled in the box under the hood. I'm not even sure it's the fuse but I want to rule it out. Anyone know the exact fuse?

Should be fuse 8 under the hood. Says park lamp.

Thank you, the fuse was fine. I was pulling my hair out trying to find any info. This site always helps me
