gas capless fill valve question
question I have a 2014 ford escape with the 2.0 motor. I have a evap leak code, i hooked up a evap smoke machine to the line behind the purge valve in the engine bay and see no smoke coming from gas capless valve on the top valve but the lower one when you open it smokes crazy. does the lower flapper valve seal also or just the top flapper? the code comes and goes when i fill depending on how i pull the gas tank nozzle out so something is telling me its that lower flapper? any one familiar?
