Meh. If the bulkhead does its job, the flames should stay behind the driver as long as the vehicle is moving forward
Reference young Mr. Emmons C/BFRMR in 2011. Caught on fire, completed the run, and took it to record cert. We were behind them in line; the consensus was "it'll buff out".
Some nerf bars might be helpful, however.
That's a big damn dry sump tank. Our C/GRMR, which is a bit quicker than your B record, only needs a 5 gallon tank and only has 4.25 gallons in the complete system. At the size you show, you can do a lot of turbo oiling! Your box looks like approx. 24 x 18 x 6 which is a bit over 11 gal.
I have a proven deaeration system for rectangular tanks using Oberg filter(s) which I'm finishing the build on currently. Don't let the round tank/swirl system guys get you crossed up.
