Changed my filters earlier in the week (OEM and Racor 690 2Mic Pre OEM). Used the GRG (Grand Rapids Guru) technique listed in the Do It Yourself section to change out the OEM. Very quick and easy. OEM had 17K on it, PreOEM had about 6K on it. Cut them open and what do I find in the OEM, well, just as warned about here, RUST, and lots of it. And were not talking your garden variety fine surface rust, no, were talking about chunks. I could have scooped it out with a spoon. I thought for a minute it was sand, or something other than rust because it was not stuck to the surface. It was that thick. The pictures do not depict how heavy it was. I wiped it away, and there were fine surface pits underneath, so it was working away at the surface. Be warned gents, all is not well in the land of OEM Fuel Filtration...but my Racor PreOEM sure looked purty.
