Have the Racor Fuel Filtration Products catalog. Am looking at the model 690 fuel filter. The Clean Pressure Drop PSI/kPa column lists this filter at 0.29psi/207kPa. What exactly does that mean? I ASSUME that it means when the filter is brand new ie clean, that the pressure drop is 0.29 psi across the filter. As the filter gets dirty, the pressure would increase to something higher. Is that the skinny? And what is the kPa equivalent? Is this the metric equivalent? Or is it the suction if measured on the suction side of a pump? I need guidance. thanks

Yes, it's the DP at some standard flow, when new.

kPa is one of the many metric pressure units (MPa, kPa, Pa, kg/cm2, bar, torr, etc.)

I hope it's really 2.07. 207 kPa is about 30 psi.

Clean Pressure Drop

You're good. I crossed lines when reading the numbers. The Racor listing is 2.0 kPa, not the 207 kPa I had. Sorry.
