You keep saying the fuel filters were changed, but I haven't seen you confirm the presence or absence of one in the Cool Fuel module which some have suggested checking. I have read some other posts where folks have had issues with that filter in the module and others that have confirmed there is no filter...so either it was removed in their cases or there are some situations where the Cool Fuel module comes equipped with one and others where it doesn't.
