Twin Engine Airplane Fuel tanks system

What type fuel tanks system works best on a twin engine airplane?

One artical that I read said, the inboard fuel tank should hold 1/2 ounce more fuel than the outboard fuel tank. Start the outboard engine first. This seems logical but I don't like idea of starting the outboard engine first and then having to set in front of it while I start the other engine. When the outboard engine runs out of fuel the airplane will fly several laps on the inboard engine. I have read several places where it says if the inboard engine runs out of fuel first the outboard engine will cause control line slack and you crash. Any suggestions?

I have been experementing. I built a bladder fuel tank that supplies fuel to both engines. On the test stand they both run out of fuel at the exact same time. The bladder works great. I built another fuel system using a weed eater carburator fuel pump to pump fuel out of a common fuel tank to both engines. I ran a hose from the muffler to the weed eater carburator to make the fuel pump work. It works on the test stand too.

I also bought 2 tiny timing belt pullies and a 1/4" timing belt. I put a timing belt behind each propeller and ran the timing belt between the 2 engines. Start one engine and they both start and run at exactly the same RPM. When one engine runs out of fuel first the other engine has enough power to keep the propellers on both engines turing but not very fast.

Now I am working on using 1 engine to turn 2 propellers with a timing belt. If this works I was thinking about building a Nobler to look like a B-17 with the engine inside the fuselage center of the wing and using timing bests to turn 4 propellers about 7" or 8" diameter each.

Seems like a dumb idea just to make something look NEAT it probably won't fly any better than 1 engine with 1 propeller but its fun to experement.

I have two twins and I find its better with the inboard engine with a slightly larger tank this way its safer to start the inboard first . some times the motors quit at the same time or within one or two laps. I recommend a twin , great sound and lots of fun.Mine are FP15's , Fits in the car and not too large.SEE YA NEAL:) P.S. keep it simple remember you have double trouble.

Gary,
I would say the single tank system would be the best route where the engines quit at the same time. I hear that Paul uses something like that in his B-17 (never "seen" it in person), and that seems to work real good!

I start my engines left handed. I don't know why, I just learned to start engines left handed. That way I am pulling down instead of pulling up, but...starting the outboard engine first left handed seems logical to me.

For someone like me, who flicks the prop more or less from right to left, it seems much safer to start with the inboard engine and work outwards. I used to take a square of heavy cardboard with me and after starting the first (inboard) engine, I would hold the carboard between the two engines resting it on the ground and steadying it with my left hand at the top while I started the outboard engine. It just acted like a wall that you can see much better than a spinning prop and for me it made starting a bit safer. I never got hurt while doing that anyway (just a broken heart when I crashed it).

We had a guy here who built a B17 and started the most outboard engine first. He then cut his hand to shreds on the running engine while trying the start the next one.
