Recommended wiring for electric fuel pump

[rmaynard 16,771]

This will be my first venture into the world of electric fuel pumps. I just received my Facet pump and want to wire it into my 1996 416-H (Onan). For those of you who have done this on similar engines, where are you tapping into for 12 volts?

@Bill D I believe it was. Recommended tapping on to the positive side of the coil feed. That way the fuel pump is connected to any safety switches that may be in play also, it gets power during the starting and running phases of the ignition switch.

Exactly.  Couldn't have said it better myself.

You did.

But... do add in inline fuse between the coil feed and the pump.

Thanks. That's what I needed.

Is this correct? What fuse is needed? 15A? 30A?

The Facet pumps have an internal circuit breaker

 

None of the pumps draw more than 4-5 amps most less.  Fuse size should be based on wire gauge.  If you use 16ga i would use 10 amp fuse 

 

make your connection to the "+" terminal on the coil

I wired one to the pink dash lights wire on a 520 so it would be fused by that circuit. Problem is as the pump pulses the (led) lights flicker in tune with the pump. I may move it to the coil but I may have a battery going south too as it kinda goes away at throttle up.
