Ok; so I fill up this week.....and down the road my gauge bounces from full to half and back, call the dealer thinking it is send unit or pump; he is not sure the setup on the 4200 coupe; says some have the parts together and some are seperate depending on which model; I guess with the Ferrari's, Astons and all he cannot keep it straight; telling me it could be from $800 to $2000 including draining the tank...........whatever Mr Stealer, ANY IDEAS, he says this is not common BUT is reported! dogdoc
