Can anyone clue me in or point me to a thread that shows what can be done to the stock lines to have the best shot at running a DW or TT340 pump and 80lb injectors without having too much of a restriction? The TT340, injectors, and chip are on their way and I've been searching for days, but only found tidbits of info. So far I know that on the feed side of the hanger in the tank a section can be cut off where it necks down and that should help increase flow to the motor. I've also read of people enlarging the line at the saginaw fittings of the return line with a drill bit, but don't know at which locations and what size bit to use. Is it also worth replacing the rubber sections of the line due to their age and the coversion to E85? I'm sticking with the stock fuel rail and billet style regulator also. Thanks.
