Can someone tell me how to bleed convertible lines?
My pump seems to work, but have air in lines.
Thanks.

You must have a hose adapter (which you can make) that will seal one end of a hose into the reservoir on the pump and the other into a vessel with fluid. Put the adapter with hose into the top motor reservoir and the other end of the hose is submersed in fluid (I use hydraulic oil or ATF is ok). Run the top motor in both directions until it clears the lines - the noise the motor makes will be more subdued as the air is eliminated from the system.

As to the adapter, I took an old nozzle adapter from one of those generic inflation tools and clipped the end from it. You could also use a nozzle from a tube of silicone with a short shunt of brass tubing to connect to the hose. The best scenario, IMHO, would be to have an extra plug for the motor/reservoir to modify.
