RE: DIY 1/4 CARS RCMK 600B
The dual tank set up might be a bad idea. If by chance, one of your tanks runs out before the other, you'll be running one of the cylinders dry. Might cause scaring of the walls of the cylinder or even cease. That was something I'd considered when building my rig and was quickly told not to by my engine guy.

I agree! That was the first thing that I thought of
but if they had a nice big open transfer tube, they might get away with it. The current packaging does not look like it's condusive to a single tank or a big transfer tube. Too bad.

I know it doesn't look condusive to using a single tank, but give it a shot. If you just tee the fuel supply lines together and the tank returns together, you might be able to get away with it, especially seeing as these carbs will pump quite a bit more fuel than they will feed into the engine.
Any ideas as to where you'll put the radiator or some form of reservoir/expansion tank? Maybe, if you could run it off one fuel tank, then you could put it where the second tank is.
I do like the idea of using a computer radiator for this. Never had thought of that as an application for them. My only question on it, are you using a true radiator design, or one of the cheaper ones that is just a long piece of tubing bent back and forth with fins on it?
P.S. When do you think that you could get a video of it running? I'd LOVE to hear that twin engine.

i'm running a twin with a single tank line to feed both carbs, i just made sure the line into the tank is more than twice the area (the bore) than the carb inlet nipple bores so it'll flowmore than required by both carbs, i then tee'd off that with smaller diameter tube to each carb
returns are slightly bigger than nipple bore, run to a common return on a "y" not had any lean issues
