Well, the aim is to pump te fuel to the carb with anything different than a muffler presure or Perry pump.
I was told that I can drill a hole into the rear plate of engine and take pressure directly from there to the tank... does it work?
Is over there another different manner?
Thanks on advance

Assuming your talking about a 2 stroke engine, it seems to me that it would be better not to lose any case pressure. I believe some of the fuel that gets sucked into the case will then get forced back out to the tank before it goes into the combustion chamber. I would think this would cause a drop in engine efficiency. The regulating perry pump prevents the case pressure and fuel from escaping. You could use the oscillating Perry pump on 4 or 2 strokes. It just goes inline to the carb inlet and sucks the fuel from the tank using the rotational oscillation of the engine to move a ball back and forth. I use one and it works great. Another alternative could be to use some kind of electric fuel pump. I know there are plenty of onboard electric smoke pumps on the market, but I'm not sure about for fuel. Seems to me like there would be.

The Cline pump/regulator system uses a pressure tap on the crankcase with a check valve to maintain the pressure in the tank. I do not think that this would work well without the regulator as the tank pressure will be on the order of several pounds.
