Honda 2 HP: Long or Short Shaft - External Fuel Tank Ideas

[Pacman]

Salty19,

I agree the tank must be vented.

My plan is to have the vent in the remote tank (with the vent on the OEM tank closed).

That way, air will flow into the vent on the remote tank as fuel is drawn into the OEM tank by the vacuum.

In theory, if the vacuum is sufficient to lift the fuel about 12 inches, it should work.

If the tank vacuum won't pull the fuel high enough I will go back to design concept #1.
