Filter
Hi David,
I will say yes. There is no better insurance for the health of your engine than filtered fuel.
I have a filter on the pick-up in my fuel can and a filter after the pump on my fuel can.
Then... there's a felt pick-up in the models fuel cell, the UAT and a fine filter (supplied with the engine) between the engine fuel pump and the engine. Your engine is worth the few bucks and extra half hour to install filters. You'll be happier too.
