I have been having priming issues with my dual line system. Takes a lot of drill speed and time to pull oil from pan initially. After sitting for a month, even the 3 qt accumulate prime didn't get it going. My pan to pump hoses were both low from pan to pump. I had to route the front (2nd) line under the pump due to the fuel injection pump being in the way. I checked the pump, and rotor to cover clearance is .004, gears look good, no serious scratches in the cover or pump body. I am going to check on ways to raise both intake lines up, so they can't drain back so easily. Any other thoughts? These are new lines and fittings.
