Without pulling the upper intake, they wouldn’t be able to see if it is the regulator leaking externally or if one of the plastic injector lines is leaking. Of the two, I’d suspect the regulator (silver thing in photo below) before the lines. It can be replaced independent of the entire injector assembly. Maybe $30 for the part?After talking to them again, they said they smelled gas up where the intake is where it attaches to the center of the motor. I'm not exactly sure what that is supposed to be. They said they didn't particularly rule out the fuel pump, but the fact that they smelled gas there made them think it might be the fuel pressure regulator or the "lines". Not sure exactly which lines those are, not the fuel lines though and he said they are plastic. I know I'm way over my head here, so any help is greatly appreciated...
One additional thought...Back in August, there was a little run where it would make this loud pop sound when starting occasionally. That went away and then Monday afternoon it did it again. But just the once. Not sure if that leans toward the fuel pressure regulator or just weird coincidence.
It’s really not a bad job should you want to do it. The only required “special” tool that comes to mind is a 1/4” inch-pound torque wrench. I’m sure there are YouTube videos that would give you an idea of the process.
