SF_SN888KE Ron have you looked into fuel cells?? The other idea I have for you is to have the fuel pump installed in the tank with foam to control the sloshing of fuel. I run FI system and have 2 electric pumps in the tank. There is no problem with racing. I keep 1/2 tank the car to cool the pumps. You can do the same thing. If you are serious about racing, you should have a 1/2" supply line to the front of the car and a 3/8" return line back to the tank. I run 2 independant fuel systems incase 1 pump acts up. You will need a fuel pressure regulator to drop the pressure to the carb. About 6 psi is all the needle can handle. You will need a relay for the pump. Seal and solder all connections. Weldon fuel pumps are the only ones that I know of can suck. I think this is also safer that to add a sump to the bottom back of the gas tank. If you get run into and crack the lines or sump, you could be cooking hotdogs and yourself.
