[FC] Electric Fuel Pump Shutoff Switch - Has anyone experienced this problem?

[phillbilt at sbcglobal.net]

maybe this will help you,if you use a oil pressure switch,make sure it has three connections,one n.o. post, one n.c. post,and one common post,if you still want to use your dummie light,connect your light to the n.c post,and common post of the switch to ground,when there is no oil pressure light will be on,connect the ground wire from the electric pump to the n.o. post,and the positive wire from pump to any 12 volts, you can use key switch,or toggle switch,so when you start and get oil pressure,the switch will ground the pump and it will run and the dummie light will go off.

 There should be no connection to the starter.
 The safety switch merely only stops connection when the oil
 pressure drops. When you start to crank it takes  a
 little while (seconds) to register oil pressure, and so you
 don't get a completed circuit for a short time, but apart
 from that so long as it has pressure it should supply the
 pump with power. On shutdown of the engine the pump will
 continue for a short time while oil pressure drops and the
 switch shuts.
 
 So wire power from the battery to one
 side of the oil pressure switch, and from the other direct
 to the pump. Then from the pump to earth.
 
 You can put an extra push to complete
 in the circuit to prime the carbs before starting, if you
 think it is taking too long to crank up pressure and get the
 pump to start.
 
 Hope that helps
 
 Cheers,
 Daren

 Shutoff Switch - Has anyone experienced this problem?
 
 Hello All; 
   
 Still experiencing a problem in trying
 to get my electric fuel pump to work in conjunction with the
 oil pressure cutoff switch (replaces standard oil pressure
 switch). 
   
 
 
     * Red lead from pump is
 connected to the "P"  lead  on oil pressure safety
 switch 
     * "S" terminal on safety
 switch is connected to "S" terminal on starter 
     * "I" terminal on safety
 switch is connected to a terminal on the fuse block that is
 hot when the ignition switch is in "on" or "start" position
 (wiring diagram shows it being connected directly to the
 ignition switch) 
 
 I have confirmed that the starter and
 electric fuel pump both work. 
   
 When I connect the wires/terminals on
 the oil pressure safety switch with a jumper wire, the
 engine turns over. 
   
 I have purchased/tested two oil
 pressure safety switches and both present the same issue. 
   
 According to what I have read online,
 there should be some sort of bypass in the switch that lets
 the engine crank before there is enough oil pressure. 
   
 Could it be that I need to connect the
 "I" terminal directly to the ignition switch? 
   
 I'm about ready to ditch the safety
 switch and wire the pump directly to the fuse block. 
   
 Any suggestions?  I am hoping to
 get it operable for the Woodward Dream Cruise Saturday - I
 live 1/4 mile away. 
   
 Thanks,
