We will be blowing the car apart for paint after the first track test, so we will likely add the painted borders (and some RTV sealant) to these windows then. For now they were secured in place with bolts only.
FUEL FILLER NECK
At this step we show the plumbing from fuel filler cap on the right rear window to the fuel cell, which had an ATL sourced top fill panel. This is shown with the partial aluminum enclosure around the aluminum fuel cell can in the picture below.
Because of the unusual back seat fuel cell location the filler neck was added to the right rear window. A simple fuel filler neck and cap were sourced from ATL and added as shown below.
Ryan took some aluminum tubing and welded a mandrel bend at the top to line up the filler tube to the cap in the window. A short piece of flexible tubing was added at the bottom but this is only silicone and will be changed out for a fuel safe flexible hose soon.
To make this filler neck fire safe the entire fuel fill section was then wrapped within a metal enclosure.
This is what it takes to put a fuel cell in the back seat - lots of fabrication work. An upper section to the fuel cell enclosure was built to tie into the fuel filler neck enclosure tube-within-a-tube. Ample room in the top enclosure was added to allow for plumbing AN lines from the fuel cell to the fuel pump and engine and back, all of which will run under the car.
All of this can be unbolted in sections for service, but most importantly fuel can be easily added outside of the car and end up in the fuel cell - with fire safe enclosures around everything. That wraps up the fuel cell can, filler neck, and enclosure. We still need a fuel cell bladder, which we have been trying to get quoted for many weeks.
