Facet solid state fuel pump's should be pre-filtered as they have no internal filter, unlike the larger Facet interupter models. These filter unions will fit all of the Facet solid state pumps, the smaller model suited to the lower pressure pumps and the larger one more suited to the competition pumps for higher capacity vehicles requiring a larger volume of fuel. They are not suitable for use with the cylindrical Facet 'Interrupter' type fuel pumps.
