Fuel pump diode

["KENNETH MASON" <meditionm@msn.com>]

Does anyone have info on the characteristics for the fuel pump diode?  With
the points held closed the coil draws about 3-amps.  I also measured only
about 0.5 amp with the diaphragm cycling and a 3-amp diode across the coil
windings.  I also notice that the diaphragm cycles much slower with the diode
in place and if I remove the diode while it is running, the amperage draw
rises to about 1.0 amps.
