I installed a new fuel valve and sediment bowl without the bowl. With the valve closed, I saw fuel dripping from the hole on the bottom of the assembly. I then swapped the stem from the old valve it looks like it stopped. I hooked a new fuel line to the side of the valve and tightened it. I opened the valve and the bowl filled without leaking around the top of the bowl, but there was a slow leak on the flare nut on the fuel line. I tightened it some more and it seemed to stop it. With no more leaks I filled the tank about quarter full and ran the tractor for about an hour using a box blade to rip up some dirt. When I went to shutoff the valve gas was dripping from the flare fitting. I put a wrench on it and it feels like it loosened a little. I tightened it again, but wit the valve open it still leaks. I donít want to break anything by over tightening it. AnybodyHey have any ideas about how to fix this. It is a 50 8N. Thanks.
