Installed the larger Aeromotive 12347 10 micron filter today. I like this filter much better than the small FAST 30272 filter as it has much greater filter capacity area. I also think it looks better under the hood. I had stopped getting fine dirt from the driver's side tank, but switching to the passenger side tank proved that one still had fine dirt in it. The FAST filter was plugging again, but not as quickly as it had before. I believe the new filter has enough area it won't stop up before all the fine dirt pumps from the passenger tank. If it does, I have a spare element ready in the glove box. Next, this old truck is hitting the road again for a final tune!
