Re: Suitcase fuel tanks

Ah, OK.. So the diaphragm pump is there to prime the carb, but it isn’t used to feed fuel to the running engine..?

Now the magnetic fuel gauge makes more sense.. they’d need another set of seals to use a purely mechanical drive.. and the torque on the fuel gauge shaft is so low, that the seals alone might create enough friction to make the gauge pretty well useless.

Yet the question remains – if they already had a diaphragm pump in use, why not integrate the pump to the motor, and implement the typical suction system used on later tanks?
