Gave up after 10 hours of bleeding the toy engine. Installed a electric fuel pump
2.5 to 4.5 psi. Works great. But engine still not cooperating. Runs on either, which is not good. Now only 1-3 are squirting fuel
. Nothing from #2. Have a full-fledged diesel man arriving on Saturday. Promises to stay with it until it runs....so I'll have to wait and see. Will let you know the results. Never ever had so much trouble with a diesel engine.
