I had the same issues with my 300zx mod now sealing. I eventually had a shop here in town build a new tank with a sump and an external pump. When I had the 300 with stock tank I had huge starvation issues at half tank while at the track on long left hand turns. So it was either that or have fuel spill out because of not sealing properly..... I eventually had a shop build me the tank, it was around $650 for them to built it. It now has external pump which is a little loud but I did seal off the back seat to help.
