Tanks Inc EFI recess size

I picked up a tank today for a 69 Cuda and started to fit the fuel pump and fuel sender unit. I measured 8.5 inches from the bottom of the tank on the inside to the top of the tank on the outside, this was for the fuel level sender unit.

Appreciate it. I was actually looking for the area around the pickup and pump holes, not really the depth, but I appreciate the info.

I gave up on the idea and bought a standard tank and am building my own pan (with help from a friend).
