Good work and it looks like you have a spot for a new battery box.

Are you able to do away with the expansion tank and charcoal filter system?  That's the only area on my car I have never tended to, I have no idea if it's actually functioning properly.

Correct, I will be doing away with the expansion tank and the charcoal canister. The loop will be simplified here is the tentative plan:

Fuel cell pickup -8an hose
prefilter -8an hose
external inline pump -8an hose
post filter -8an hose
-8an bulkead to underbody
-8an to 1/2" adapter
1/2" aluminum fuel line to engine bay(overkill but its what I had on hand)
Convert back to -8an
Nuke fuel rail -8an inlet
Nuke fuel rail -8an outlet hose
Aeromotive fuel pressure regulator inlet -8an
Aeromotive fuel pressure regulator outlet -8an
Convert back to 1/2" AL to bulkhead to reenter trunk
Bulkead -8an to fuel return on fuel cell.
-8an hose fuel VENT to bulkead exiting trunk to fuel vent on stock fuel filler

Cut the aluminum plate which will be the mount for pump and filters. Drilled and tapped for 5mm bolts. Hopefully the rest of the fuel system parts will come in so I can finish this mockup and move on to the next area.

Got a package... I thought I converted my cash to gold but all that was in the package were these connectors:

AN connectors are about as close to gold as you can get :)

Exactly, I didn't realize what they were getting for these things until I started the order then was a bit shocked to see the total. They are mighty proud of AN connectors! 

Hopefully I will have this mocked up this weekend. Thought it would be a good idea to throw a surge tank in the mix since there are no baffles in my fuel cell. So I need to fab one up. Two ideas a 4" cylinder about 8" long or a 5"x5" square tank. We shall see which direction I go Saturday morning.

Didn't get the tank finished ran out of fittings. Somehow I only got 3 of 4 weld in bungs. Also, need more various fittings. But, here is what it looks like so far.

Final mockup:




Stock fuel filler and location fab work. Chopped up my old 98m3 exhaust which was a perfect fit onto the stock e30 fuel filler and RCI filler neck.
