Kevin Moore Posted April 30, 2008 Share Posted April 30, 2008 Never having used a pumped engine before Iv'e always had a feed going to the exhaust to feed pressure to the tank. Obviously this engine is pumped so no feed to exaust but it needs to have a vent. What's the best way to stop fuel exiting from the tank vent pipe? Will a one way valve do the trick or is there some other way. Any help or suggestions appreciated. Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted May 24, 2008 Share Posted May 24, 2008 Hi Kevin .If you use a small vent to the tank( Air will pass through a very small opening ) the tank will be able to breath and due to the fuel being drawn by the engine ,fuel will not come out of the breather.I have in the past put a building pin in the end of a piece of metal fuel tube then squeezed in the tube around it , when the pin is removed it leaves an ample hole for air to enter and no fuel (or very little )will come out of it. I fit this pipe to the fuslage and connect with normal fuel tubing to the tank . Dont forget you dont need a pressure pipe to the exhaust on a pumped motor.
