I had a fuel leak thought it was coming from bad hoses replaced hoses and notice it was coming from under the fuel bowl so I removed the bowl to find a perfect hole not even a 32 of inch wide looks like there may of been a plug in it. So I put JB Weld onit my question is will the JB Weld hold up to the diesel or is there a kit that comes with that little plug

 

well it should hold up to the fuel. but if you didn't get it super clean it just won't stick...
