The Fulvia hasn’t been running smoothly as so thought I’d change plugs, air filter and fuel filter. However my car doesn’t appear to have one of the inline plastic filters.
Where’s the best place to fit one - in the rubber line exiting the metal fuel and before the pump or in the post-pump tubing under the air box somewhere ? In fact are they useful, required? The car was “restored” before I bought it but I have no idea how the fuel system was cleaned up.
Is it possible because of a lack of a filter that gunge has got into the carbs or elsewhere to cause the rough running?
