Raf Posted June 27, 2014 Report Share Posted June 27, 2014 Hi guys, I found this one hanging not connected to anything. Can anyone point me to where it should connect to? it's right by the oil dipstick on a yamaha 40hp 4-stroke Link to comment Share on other sites More sharing options...

aplumma Posted June 28, 2014 Report Share Posted June 28, 2014 Open the brass screw 1/2 turn it should let fuel flow out if it is what I think it is. If it does it is the bleed down for the carb. If no fuel then re close the screw 1/2 turn and I have guessed wrong. Art Link to comment Share on other sites More sharing options...
Raf Posted June 28, 2014 Author Report Share Posted June 28, 2014 Art this is a fuel inject motor. Tho that doesnt mean you are wrong. If I do turn it and fuel comes out what do I do with it Link to comment Share on other sites More sharing options...
mike rousseau Posted June 28, 2014 Report Share Posted June 28, 2014 Looks like a fuel drain line to me Link to comment Share on other sites More sharing options...
Raf Posted June 28, 2014 Author Report Share Posted June 28, 2014 (edited) well, I will feel silly (but relieved) if that's what it is. i'll give the screw a quick turn tomorrow and if i get fuel coming out i guess it is safe to assume it's the drain Edited June 28, 2014 by Raf Link to comment Share on other sites More sharing options...
TennesseeGuy Posted June 28, 2014 Report Share Posted June 28, 2014 Possibly in place to drain ethanol gas before it does more harm. Link to comment Share on other sites More sharing options...
aplumma Posted June 28, 2014 Report Share Posted June 28, 2014 Yes it also applies to fuel Injected motors I am used to working on the carb. engines because it is what I own. Same principle though. Art Link to comment Share on other sites More sharing options...
