They don't cost that much. Don't risk it.. Just change the filter... It took me less than 30 mins and $20 filter from Ebay.
Modern cars have a filter that you cannot clean. Replacement is the only option. Usually cheap enough.
No its just to clean your injectors the fuel injector cleaner will just go right through the filter it wont do anything to filter.
You don't clean them...you buy a new one.
you don't clean fuel filters you replace them
