Product Reviews      Review part 81-1005

 We recently built a replacement oil tank for a dry sump system in an historic Indy car. Since the Cosworth DFX engine in this car is quite expensive, we used this filter between the tank and the suction side of the oil pump to ensure that the pump would not ingest any foreign material left inside the tank such as aluminum chips. Although we cleaned the tank well, we wanted some extra insurance. On a weekend at the track, the filter worked just as planned. The oil pump is free and clear of debris and we saw no drop in pressure. The filter worked perfectly for this application.
