I have a 1999 vmax 500 ERC. Engine fried and I have completely rebuilt it. When taking the engine out of the sled I noticed the oil line coming from the oil pump to the fuel pump was full of gas and not oil. After rebuilding the motor and reinstalling everything, I bled the incoming oil line to the oil pump and the pump itself. When I pulled the out going line off the oil pump to bleed it, it was full of gas again. After putting a 50-1 mix of oil in the gas tank to protect the engine, I started it and pulled the oil line off the fuel pump. I had a steady stream of gas out of the fuel pump and no oil from the oil pump. I had a second oil pump and swapped them out and ended up with the same problem. The engine runs great so the fuel pump is working but not sure why the stream of gas is coming out of the fuel pump when I pull the oil line. Is this normal or is part of the fuel pump not working? I don't believe I have 2 bad oil pumps? What am I missing? Thanks in advance!!!!
