I capped off the vacuum line going into cab and put thread sealant on both ends of the fuel line. I believe it might be a little better, probably my imagination. So I guess the carb has gas leaking in many areas so guess that is the next project. I might message Jon the carb guy to see what turn around time would be. And of course fuel pump will also need some work. It appears to be leaking fuel around the 6 screws. The hissing did go away 😎
Thanks Glen
