truck mods in sig. i have a fuel gauge and it's not happy with the current stock system. what di i go with also i want the extra filter if i go with the fass. also do i need bigger lines, and do i have a pump in the tank if my lift pump is on the motor also. Tell me what you guys think i need if it were your truck. i am planning on stepping up the injectors, and adding a set of dragon flow 150's also.
