Re: M11 Fuel Filter Replacement Process
Reply #8 –
No need to fill filters. Depress air vent and vent air out with air purge button. Filter on engine will fill and return air back to tank. Common rail engine. The four o-rings on the clear screen do fail. Replace and keep spares. I like DC4 on the filter seals, makes removal much better. I destroyed a filter wrench on the engine mounted filter prying it off. I like to carry spares for all.
