Cox .049 fuel tank


Hey all.

So I have a RC Cox .049 and I am wondering how to setup a fuel tank for this. I have only ever dealt with bigger engines which have a muffler to supply pressure for the tank.

Is there a right or wrong way to set one up. Can anyone point me in the right direction.

Regards,

Glenn

Keep the fuel tank distance from the engine as short as possible and approximately even with the intake on the engine (the center of the back usually). Then just run it. The engines are setup to run without muffler pressure. But if you have a muffler for one that has the metal cap, you could fit a pressure fitting on it for muffler pressure. But no one typically does so. With the Tee Dee engines, if needed, the guys usually for for crankcase pressure or use a bladder to provide the pressure. But even the TeeDee engines run pretty good without muffler pressure.

Excellent. Sounds pretty simple.

Looks like i'll only have 2 lines to do. One to the intake and one for filling. Sounds good to me

Thanks guys.

Nope .. use a balloon tank.. a 9 inch one from the $ store.
With one perforated feed tube (end of the fuel line) inserted in it.
A rubber band securing it to the fuel tube extending out from it's innards.
Fill it with fuel.. No pressure, just fill it, It's a bladder tank but not a pressure bladder one
So you end up with a perfect fuel supply, needing only one line and No draw or foaming issues.
