you may want to make the take out of .090 3003 alum or 16 gauge pickled steel you can add two baffles. i punch some holes in the baffle walls . for drag racing you want the pick ups in the back of the tank and at the bottom or the bottom to the back side. you can make a sump to pick up the fuel at the lowest point you will need some bungs you can make them or buy then for racing you want two for fuel AN8 or 10 and one vent at the top AN 6 and i run the float on the sender front to back so the fuel will not work the float side ways when the fuel moves back and forth
