electric fuel pump

I was working on a 96 Jeep Cherokee and found it has a single fuel line from electric pump mounted in the tank. It's pressure regularter in mounted on top the pump sender assembly and dumps excess back into the tank. The only drwa back is that tank is 12 inches deep. I dont mind loosing the spare tire well since the spare doesn't fit in it anyway but, even that isn't enough space. The trunk floor would need to be raised 3 more inches. So close and yet so far. :(
