In my project, I will also need to pump the additive to the needle valve. I was thinking on a electric fuel pump from our every day cars, but this are too big and powerful ..., then I thought again in the RC world and found some pumps I think that are used only to refill the plane/car/helli.

What do you say about this pumps?!? I think they would not like to work 3 or 4 hours in a row and would break very soon.

Is there any electric pumps in the RC world used to take the fuel from the fuel tank to the engine carburator of the car/plane? If there are any, that would be the ideal pump to my small project
