I just went through this. Replaced my blue holley pump with a black holley. Had a Mallory filter with paper element before pump but was told by holley that you should never use a paper element before the pump even though Mallory and BG use paper before their pumps. Who knows. Holley recommends a screen type filter before the pump to make sure you don't get any cavitating of fule at the pump. At any rate I really didn't have room for the paper element filter without running the line up hill which I was trying to fix. I ended up getting an Earl's in line filter with a stainless steel mesh screen (85 microns). Was able to easily plumb it inline with my -8 line before the pump. I screen my fuel when I put it in the cell as well, so I didn't really see any point of running any other tighter mesh filter after the pump.
