Fuel wator separator filter???

[Chamberpains]

I use a 10 micron filter on my 870. The filter plugs pretty often (7k-8k miles) so I keep two or three spare ones in the truck.

I used to change it when it would get to the change line on the the top of the Davco clear filter housing (every 5k or so) but lately I noticed the check engine light for a plugged fuel filter will come on long before a shutdown or stutter problem occurs so I run it clear until the light comes on then I change it ASAP and that gives me a little extra life out of the filter. I'm currently monitoring to see if I'm losing anything doing it this way. So far no adverse effects that I've noticed have happened.
