You are either starving the pump, the pump is shot or u may have a regulator problem. Id start with checking for air on the suction side of your pump(s) and making sure both your filters are clean. If no air and clean Id drain the oil thru a fine strainer and see if any fragmentation falls out. If it does then i feel for ya cause that would indicate the pump is shelling off metal and your engine is trashed. If the oil is clean then id thank God for your good luck, rebuild that pump and replace the regulators. Rawze and Haggai may have better advice. But definitely start with air bubbles and filters. Those davco canisters can sometimes be real finicky about sealing up and let air in around the orings so make sure the orings are seated and lubricated and the nut is tight.
