the stock fuel system works fine on a nearly stock engine, it generally won,t keep up with the needs of an engine with double or tripple the orriginal power levels

btw theres a tendency for new guys to cut a large square hole in the tank floor when welding this type of sump to the original tank floor, thats a very BAD idea, it lowers the structural strength, the correct way is to drill about 4-5 3/4" holes in the floor of the old tank slightly nearer the shallow end of the sump from the center line of the sump in the old tank floor,so fuel falls in and is trapped under high G forces durring accelleration and braking, this also tends to limit the tank floor from warping due to heat durring the weld process, (you should tack weld about 8 spaced welds then fill/weld each area between the tack welds skipping diagonally as you go to limit heat/warp
