The details:
'65 Series IIA 109.
Weber 34 ICH carb.
The problem:
Engine idles fine but stutters and stalls under load. The problem began suddenly back in the winter and hasn't been resolved.
So far I have disassembled the carb and cleaned it completely and ruled that out as the problem. When idling the fuel filter container is about half full of fuel, but after driving down the road a few dozen yards and experiencing the stuttering and near-stalling, the fuel filter container has very little fuel in it. So next in line as a culprit is the fuel pump. BUT . . . the part that should be the fuel pump looks nothing like what Rovers North is selling as a mechanical fuel pump. What I am seeing looks like the attached images.
It doesn't have the glass reservoir on the side like the mechanical fuel pumps pictured in the Haynes manual or the catalog.
What is this part?
