Help with stock EFI

Yea maybe about that on a stock trunk pan. Mine was hacked up when I got it so I don’t have a great reference really. But the FPR sits about 1-1/2” off the top of the tank if that helps.
Thanks for the info. Not trying to hijack but maybe would give Truckie ideas too...What did you do for flange? Tabs or cut out from a stock tank? Did you make a custom gasket, cork or rubber? How did it hold up re leaks when tank full? Thanks in advance.
