Remember the problem Ed Anderson had.......When oil pump pulley was

installed the key was pushed out of the keyway and he was flying for a

period of time with just the friction of the taper between the oilpump shaft

and the pulley driveing the pump.......Something to consider......

Got (some) oil flow.

Remove the pick-up tube and cleaned off Hylomar. Cut a new gasket out of some gasket stock I had lying around and installed pick-up tube without any sealant.

Hooked up starter (plugs removed) and spun engine, no joy. Removed outlet hose and primed pump again. Got oil flow. Reconnected oil line and left it slightly loose and had oil pressure gauge sender out. Cranked engine, oil flowed out of pressure sender hole. Let engine set while bat recharged some. Tried again, no oil.

Repeated priming and had oil flow, reconnected line and this time oil flow was good. Put oil pressure sender on and cranked engine, had oil flow. Let engine set several minutes, cranked again, had oil flow. Let set some more, no flow while cranking.
