Fuel filters

[Basfis]

I'll start by saying this is fear based. 

Blew one up this week, replacing it with a freshly built direct injected engine. 

I doubt the gas in my tank caused the issue at hand since it put a hole in the block but (back to the fear part) I'm wanting to hedge my bets on fuel cleanliness and avoid pump/injector problems. Thinking about adding another 10 micron fuel filter in the bilge area. 

Any cons?
