Well, I whipped up a quick tank for the next BDR. It should be about two gallons. It’s not 100% completed. I need to add the fill cap. This will be for sale after I get back if anyone is interested.
Lefthander chassis and Coleman racing usually have a pretty good selection of 'build' parts available. Don't forget your piss bottle, with all that fuel unless you are some kind of Hercules you'll need to drain the radiator
