03 Panther 570 ESR-same as Z570 engine
i have a air bubble in the small hose that goes from the oil pump to the fuel pump. i just replaced the oil hose from the oil tank to the oil pump and the hose from the oil pump to the fuel pump,,and the fuel pump was also replaced (with a used unit). i did bleed the oil pump first and i do have premix in the tank. however, the hose from the oil pump to the fuel pump is filled with oil except for about a 1" long air bubble in the middle. i ran it the other day and I had the oil pump cable pulled to the full flow limit just to get the oil flowing,,,but now i notice this air bubble. any suggestions.
