I have no idea what my fuel consumption will be yet! I must admit the tank does look a little small. The reason for the sump is primarily to avoid using a "swirl pot" and the attendant low pressure setup. The theory is that the sump will provide protection against fuel starvation on braking/cornering thus eliminating the need for the swirl pot. I am considering a dual parallel HP fuel pump setup (overkill though) and just a simple LP return line to tank.
I am also wondering if I (or one of you genii) can come up with a "running on reserve" light system so when the main tank finally empties a light on the dash comes on. Thats why I would like a larger volume sump - so that I have some chance of refilling before running out!
