if you FPR didnt come with a fuel guage then you'll need to rent one from AZ. once you have it attach it and do as instructed above. there is usually a nut you need to loosen first to turn the hex screw. i wont comment whether or not you need more fuel. it appears that way with your mods, but your best off having it tuned at this point to pull out all the HP from your current mods.
