Greetings,
removed this external pump from my 79 OB and discovered a post had broken off.

I'd replace it. It's the wrong pump anyway

agreed. get a new pump. I'm not a fetishest who worries about replacement parts being "original" .
If I wanted a pump or filter or accumulator I would research all that would do the job and easy to slip in. -but then I might also use VW or Briggs and Stratton valves

Drill and tap, you've got nothing to loose.

If I plan to run with just an external pump (which I do) what model pump should I get?

Bosch says..for CIS cars -

Fuel Pump 0 580 254 984 > 6/80
0 580 254 053 7/80 >

Pumps that go 0580 464 xxx are listed for LH systems, BUT they will work - my CIS car ran for 10 years with an LH pump, performed fine, in a hot climate - ie they will give you enough flow and system pressure.

Thanks!!

I believe you will need to use an external check valve if going with the late style pump. The early CIS pumps have it built in.

That looks like a wabro pump. Way exceeds the performance spec and costs about 1/4 as much as the bosch. 'Merican made dammit.
