Fuel Cell halfway installed

I bought a used 15 gallon fuel cell from my neighbor and got it halfway in the car. It's no "Fuel Safe" cell, but it will do the job well without costing $700. I first used the plasma cutter to get rid of the spare tire well, then I cut a circle of 20 gauge steel to cover the hole. I used a spot-weld method to attach it to the car, which worked much better than I thought it was going to. Now there is a ton of room under the car for a diffuser...if I ever get around to making one.

I cut a hole in the new steel to make room for the sump on the bottom of the tank. I am planning on routing the lines into the trunk to a fuel pump, then back under the car to the fuel rail. The removal of the old tank will hopefully shed some more weight as well as make some room for my side-exit exhaust I'm planning.
