before i put on my fast 90/90 i was talking to the mechanic and he told me you have to adjust the fuel lines or rails when you put it on i was just curious what you actually have to adjust because he wouldnt tell me any help would be great

 

Im not sure if you can re-use your stock fuel rails, and if you can it wouldn't look good because you would have the crossover 6 inches over the intake. I bought proffesional products fuel rail kit from ebay for just under $200 bucks. Came with rails, regulator, crossover, and alot of fittings. Check out my post.
