I had done an inspection of my tank and found no leaks. So the day after I ran a full tank of fuel and no problems. Today I did a taxi test and after engine quit after a fuel tank; I found fuel coming out the back of my spad deboniar. I'm pretty close to putting a new tank that I bought for another plane and getting fuel lines from my jug and pump. I did enlarge the holes that the lines come out of; I guess we'll see if that did it. I tried to look for a hole in the lines; and found nothin. any suggestion on what it could be.
