Look at the liner for scratches..
Yes, I was talking about by-passing the return connector, just like you described..
BE CAREFUL w/ piggy backing an electric lift pump.. IF the pressure is to great, the check ball seats in the UP position, actually blocking OFF the return fuel.. causing extreme internal pressure & blowing out the front seals.. THEN you have 20 gallons of diesel fuel in the OIL..
Seen it happen MORE THAN once.. THATS WHY I said, the check ball return on a DPA is more trouble than its worth..
I've seen it happen w/ just trash in the pump.. & I've seen it on the test stand after a rebuild..[faulty connector]
