The Lehman 120 operator's and service manuals describe the bleeding process. Basically you start at the back and work forward. If you can't get the manual lever on the fuel lift pump to move fuel for bleeding purposes, bump the engine on the starter to put the pump activating arm on another part of the cam it rides on.

Some people feel it's important to bleed the injectors once the secondary filters and injection pump have been bled. I think that's dependent on the individual engine. We've never had to bleed our injectors after bleeing the secondaries and injection pump, but some engines may need this.
