I'm considering options for a filter upgrade. My primary filter is presently a Racor 110A. I know everyone recommends the Racor 500 turbine, but the 50 gallon per hour rating seems a bit excessive since I burn less than 50 gallons a year, and I don't think the amount of flow my 3GM30F will pull will be enough to make the turbine feature even work. The price seems right on a spin on like the Racor 220, but I get the feeling they're not widely liked. Why is that? Is there some substantial problem I'm not seeing since I haven't lived with one?
