So, the fuel cell.
The cell supplied by the owner was tweaked and wouldn't sit properly in the trunk, and had the same issue in other chassis it was tried in.
Not a problem, really, since we're replicating the dual through-hood dry breaks of the historic car:
The Mary Stuart, being an evolved 1973 RSR, used a 110L plastic tank, like so (shown here modified for dual fills)
We're using a cell so that the car can be raced safely. This presents an issue, as the cell, as-designed, sits too far forward and must be relocated for the fills to work in their original locations.
Here's the client's cell - you can see where it was making contact with the body and wore through the paint previously:
I stripped the paint and started cutting off the mounting tabs this morning.
I taped the top so I could mark all over it; not certain of the approach we'd need to take. In the end I took a wedge off of the rear bottom edge of the cell, allowing the rear to move downward, elevated the front, and moved it toward the center of the car.
Here is how it will sit, compared to an unmodified version:
This is why that is important: the 110l tank (shown here installed in the project car) sits much closer to the shelf - we need to be even closer to put the fills into the cell - we have to get around the perimeter screws and fill plate bolts!
A lot of high-level math (not really) later, and we are certain this will all work.
