Cust experienced even more than lean conditions after putting fuel tuner on (worked correctly for a month or more) after trouble shooting over phone. Found out that he had back filled his fuel tank with several inches of mud and crap that had come through the tank vent which was routed down by the hitch. This will lead to weak psi and possibly the replacement of a pretty expensive fuel pump/tank cleansing.
Not really sure on condition like time spent in the muck etc and i think its the same components of the older grizz (roll over valve etc) it may just be routing placement of vent line or his had a hole in it. Maybe his tank has a hole in it somewhere not really sure
basically opening discussion on it for you guys it could save a lot of people a $1000 repair bill. for just moving placement of tank vent, or it may just be isolated case.
Anyone else experience this?
