Hocky Puck Pump
The pump only has three connections. Fuel in, fuel out and crankcase hose.
You can tell as you can blow into one connection (fuel in) the air comes out one (fuel out) and the third one (pulse inlet)
If you didn't connect the pulse line to a tee, I think it would blow off the line or build crank case pressure and force oil past the rings?
The pump doesn't take much force to operate and the vent to the carb. inlet is needed to burn the blowby from the crankcase,
Consider it only works because it is a one cylinder engine. The volume of the crankcase changes as the piston goes up and down. On a two cylinder as one pistion goes down, the other one goes up.
I would think one large tank would be the best arrangement. As each tank needs a vent, the transfer pump, electric or pulse powered would over fill the main tank and leak out its vented cap.
Good luck.

do you suppose that if necessary the line from the crankcase can be run straight to the pump thereby completely bypassing the air filter without causing problems?
