I went to a plastic fuel cell, but only because the fuel in my original '62 tank was so varnished I was afraid to run the stock one. Not to mention I knew it really needed to have a sump for the hard launches. I wouldn't be afraid to run E85 in a stock steel tank though. Out in the garage again today... hoping to finalize the hot side routing at least for the passenger side. There will be two different hot sides for the driver side. One for manual steering, and one for power steering. Those will be next on my to-do list. After that the hot side will go to the mandrel bender for costing/manufacturing tweaks. Depending on how quickly things go, I will probably start my season with my old S475 stuff, but am hoping to get my kit in my car for initial testing mid-summer.
