I have a fuel
line that seems to be breaking the laws of physics: the fuel
return line has a "T" join in it, one line returns the fuel to the tank, while the other works as a breather, hanging well above the level of the tank. Today I was changing the filters and noticed that the bilge
had a fair amount of diesel
in it. The fuel, instead of returning to the tank, was being pushed out of the breather pipe. "Simple", I thought... a blockage somewhere. I have since changed all the pipes. no blockage at all, the breather is where it has always been, about 50cm above the tank. Yet the fuel still spills from the breather. I am baffled......
If this persists, does anyone know if it would be a bad idea to remove the "T", fit the return line directly to the tank and put a breather pipe directly onto the tank?
