Default Thunder Tiger Fuel Tank Question

Guys / Anyone

I am in the middle of converting an electric motorcycle to a nitro bike. I purchased a ThunderTiger fuel tank for it but I have a question. I see two (2) air intake lines and of course the output line which provides fuel to the motor.

I don't understand why there is two air input lines and I'm not sure what to do with the 2nd unused one. So, I connected a short piece of fuel hose to the 2nd line and clamped it off with a alligator clip.

Also, when I try to provide fuel to the motor (by blowing air into the air intake line) I feel the tank expand with air but no fuel flows to the motor.

Oh, a thought just occurred to me that maybe the carburetor/throttle valve is closed to tightly?

Can anyone provide any help here?

One line is to fill the tank and needs blocking once the tank is full,the other extends to the pressure nipple on the exhaust.
Make sure the clunk weight clears the end of the tank.

the stock tank don't work well and the fuel pressure is not very constant. And as soon as the front end hit something it will hit the fuel outlet and break it....... I am using a aluminum fuel tanks which works much better.

Yes, I think I am experiencing what you are talking about as far as the tank pressure. If I place the tank below the motor no fuel seems to get to the carb and if I place the tank above the motor, it floods with fuel. Fuel just seems to drip out of the carb.

So, can you tell me where I can get one of these aluminim tanks?

Any idea where to get a new fuel outlet for these tanks?
Or maybe a way to kludge one up?
