Since Prevost has had this problem for a long time, we need to get them off the dime and make them do a recall at their expense. Since the great state of CA is loaded with environmentalists that are more anal than anyone on this site, maybe if they knew every Prevost pukes fuel, and damges the environment we could get them to educate Prevost by initiating some enforcement action.
