Hello!
As Ed Smith says ..the Uniflow tank is the way to go .... sad thing so many of todays R/C flyers doesn't know basic CL facts..
I have used this 3 line tanksystem (2 clunks, one for pressure and one going to the carb, 1 overflow tubing going up at the top of the tank ..for 25 years now and it certainly has worked good.
It is good to have the pressure hose with its clunk a little shorter than the clunk hose going to the carb...that way you don't get air bubbles into the carb hose.
The two clunk hoses will not interfere with eachother!
Filling the tank on a airplane with a cowl were you can't get to the carb requiers a fourth fuel line and this just goes into the tank. This fourth line is plugged when your are running the engine..often this line is hanging under the cowl..plugged by a 3mm screw. The owerflow line is also hanging beside it ...it is also plugged by a 3mm screw when flying/running the engine
You fill the tank with the engine at idle ...that way no fuel is going to the carb...flooding the engine!
Forget T-fittings and fuel-dots...get rid of all the things that can make you crasch!!! Keep it Simple!!
