Fuel filter before and after pump?

[BigSix]

Would anyone recommend against running 2 of those small plastic filters on my 305E? I am running the stock pump on the front of the block. Reason I ask is because a newish Airtex pump I had on their just died. When I pump it by hand lots of gunk comes out. My truck had been sitting for a while so I figure theres some stuff up high on the tank sides and when I fill up its slowly coming down. If I could put 2 filters I think I would protect the new Carter pump and the post Carter filter would further catch more junk. Truck runs great (until pump died yesterday and all I saw air pumping into the post pump filter). The previous owner had put only 1 filter after the pump...I think 2 inline filters should really restrict so much that its noticeable but I would love to know if you guys have had any issues or tried.

P.S. I believe I have 5/16" rubber line on the truck which attaches the metal line to the fuel pump.
