i removed the pump made a block-off plate and filled the cavity with oil till it would take no more..then took a small ride and it pushed air and oil out the little bleed hole in top of line up by the bars....so i called the dealer and they said to put the pump on and plug small lines and fill with oil so i built a oil tank with one line going to pump and other to the upper line above the pump making a loop to tank...so then i set pump arm slightly higher than the idle mark and fired the sled heres the problem it pushes air bubbles out the top line into the tank after four times running for a few minutes it still blows bubbles up the line into tank...i wanna know should the cavity be full of oil?or should the oil circulate?i would have left injection on but after installing new u-cooler all the hoses come up below the stock oil tank..any help would be appreciated....
