I have an MG Maestro 1600 which hasn't been started for a couple of years and I am currently working through the issues on the iginition (spark, fuel, etc.)
These cars (R-Series) have a mechanical fuel pump located on the cam cover and mine seems to have failed (which I have read can happen if they are left unused). I bought a new-old-stock one on ebay and tried to fit that and there is an insulation block missing from the new one which I cannot get off the old one.
Before I spend a lot of time cutting this block off the old one, I thought I'd test the new one. According to the Haynes manual you can manually test them by fitting the inlet pipe and moving the little arm up and down and if the pump is working, fuel will come through. So I tested my old one, the new one and a third one I found in the garage. With all three of them, no fuel came through (there is some in the tank!)
So has anyone ever done this test or is this a myth? Do they only work when operated by the cam at much higher speed than I can wiggle the arm?
