Need some advice on an irritating issue. My wife's 09 Fiat Scudo needs a new fuel filter as part of a service. The garage tried to undo the top of the plastic housing but it would not budge without permanently damaging the darn thing. All clips online tell you to just unscrew it. I tried and 'no way, Jose'. Tried heat, WD40 and silicon spray. A new housing is £147. Any tips?
