Hi Netters, Auto's for the most part use filters to provent foreign matter from entering the carb, or injectors. All of the commercial light that I have worked on over the years do not use auto style filters. Most use a combination of finger strainers (Spruce P/N 17700) and gasolators(Spruce P/N 10580). Both of these are designed to block objects while allowing fuel to still flow in spite of the fact that an object is present, except where an extreme condition exists. the finger strainer resembal chicken wire(smaller mesh) welded to an AN fitting in he shape of a cone.. They are installed into the tank such that a couple of inches are sitting high into the tank rather then as a funnel into the line exiting the tank. The gasolators usually are combined with a quick drain and located at a low point in the system to trap water and sediment. The filtering screen of a gasolator can be as fine as a 70 Micron mech, and is designed to be serviced (cleaned) at an intervial of 50 to 100 hours. As for inline auto filters, It is my personal opinion that since they were not designed for aviation fuels, there is no way to tell if the filtering material would stand up to our particular blend. A big argument against using these aviation products is that they cost a lot more then the $5.00 auto filters. I always remind myself that Corn Fields are not kind to KR's Orma L. Robbins AP/IA
