There is a filter in the gas lines already right after the tank, it had a little gunk in it but wasn't bad. I was able to replace a few of the tempo lines but looking at them they actually looked brand new...I know they still need to be replaced but I'm not doing it until I have someone watching over/helping me in the tight spots. That's what worries me the most with all the other lines and cables and what not running now through there. I will learn as I go!! This is my first ski so I will be asking plenty of dumb questions lmao. Will post more pics in the am of the inside of the hull. Thanks for all the help guys, you are all much more relaxed and much more help than ppl on the truck forum I'm on as well lol
