I was saying disconnect the fuel
lines on the diaphragm
pump, but if you don't have a block off plate or something then you can't remove the pump.
Most pumps operate off an arm running on a lobe on the cam put there for this purpose and simply removing the pump and installing a block off plate is sufficient, but some engines, small block Chevy comes to mind have a push rod that transfers the movement from the cam to the pump, so that push rod ought to be removed as well.
If you have a diaphragm
fail, 99 times out or 100 you can simply disconnect the fuel
lines, connect them to an electric pump
and drive on, after changing the oil
and filter of course.
