Two cut-off wheels later, the rear floorpan is out of the car, and as with everything on this project, there's a couple of small problems. First, the rear sway bar and exhaust hangar sit a bit farther back than originally anticipated, so the tank might have to either sit a bit farther back, or a bit higher, than I'd prefer. I probably wouldn't have this problem if I had gone with the 13 gallon fuel cell, but I'm just not willing to sacrifice that much fuel capacity; I would have gone with a 20 gallon tank if I had thought it could fit.
Next up: finish trimming the floorpan and rear wall a bit more, get the rear fascia and taillights off the car, and figure out the cell mounting position. From that, I can map out the lines and pump mounting; first indications are that I'll end up mounting the pumps horizontally where the original tank used to be, and the lines will probably end up running through the fake aluminum floorpan I'm planning on bolting in where the old steel pan used to be (around the fuel cell). I also ought to get the aluminum hard lines attached to the main floorpan with their fittings, and get the AccuSump mounted up where I want it. Once the engine is here, I can get the final line run done. Hmm, I should probably mock something up in the oil cooler location to get some idea of how much space I have to play with, too.
Still needed: at least one fuel pressure sensor with remote gauge and a 5-bar MAP sensor of some kind, for logging.
