Hello My wives 73 square has come up with a hiccup. I was driving it the other day and it just stalls momentarily as if it has lost fuel supply. I have checked most connections and hot wired the fuel pump to the ignition (to bypass the relay circuit), but the problem is still there. I have noticed that the pump is whirring somewhat (you can actually hear it while driving) louder than usual. It also seems to vary speed somewhat while idling maybe +- 50-75 rpm and one can hear the pump change rpm in unison with the engine rpm. I noticed this when I grabbed a hold of the pump with engine running to check the electrical connector for bad connection. It seems to whir up and down a bit and the engine follows it. Could this be a sign of a pending pump failure?
