I just finished installing a Livernois Methanol injection system and it took awhile for the pump to prime. The light turned green and the motor bogged down so it appeared to be working. I check for leaks and find one fitting at the pump was leaking so I tightened it a little and still leaked. So I removed the hose and re-attached. Drained the meth tank in the process so re-filled it after. Appears there are no leaks so try it again and now the pump is refusing to prime? Tank is higher than the pump so it should gravity feed. Any suggestions? I have emailed both Alky control systems and Livernois but since its a holiday weekend not sure I will get a timely reply.
