Hey Myrt/Anyone else who has a similar issue.
My machine would sometimes start and run for a few seconds, but die shortly after. Changing the fuel injector helped a bit, but chasing far too many other parts to find this...
The o-ring this guy is referencing is between the fuel pump itself, and the plastic "pump assembly" within the tank. If you take the assembly out and look where the actual pump connects to the white plastic, you'll probably see the o-ring extruded out of place a little bit (see pic)
If you take the fuel pump assembly out, pop the cap off the bottom of the assembly by gently prying the clips. Slide the pump out (again, carefully as the wires look pretty dainty). Then slide the plastic ring, and you'll be able to either re-seat the o-ring, or just replace it if it was crimped like mine was.
Screwing the fuel pump assembly back into place was the hardest part -- gotta get that gasket perfect as rain seems to be funneled directly to the top of the assembly...
