carb to fi or tpi tank question ???????????

[biglou55]

actually it is probably the other way around. can i run a fi or tpi tank with the sender and pump in the tank for a carb motor by just using an adjustable gas regulator. or does return line problems rear it's ugly head. does fi or tpi require vented or non vented tanks. I know one of us on this board has probably done this with success. what is the difference between a fi and a tpi tank.
