You have to crawl under the dash and fill it in the top. They (Bullet) did not install the remote fill plug like all or most other brands do. I would say they didn’t want to drill another hole to mount it and mess up the clean lines of the console. Mine came with the remote kit but I haven’t installed it yet either and I need to add a little fluid to mine to top it back off after an end cap came loose a couple turns when I drove the bumpy ass roads to Texas last month.
