Switched Power Location for Efuel controller

I am working to get my DIY efuel done this weekend. I have all the parts and pieces collected, just need to put it all in.

Im having a little trouble finding a solid source for switched power for my fuel pump controller. I decided to go with a controller that uses a tach signal to control the pump and it requires both a constant and a 12v switched power source. The switched power is to prime the pump for 3 seconds when key is flicked to acc. Does anyone have a fuse location or anywhere to tap in to get this kind of power. My initial thought was glow plug but i didnt know if that would cause problems.

Fuel Pump Safety Switch Here is the link for the controller itself and below is the installation instructions just so everyone can get a look.

Thanks all.

Use the old fuel heater wire.

Where are you going to get your tach signal?

Re: Switched Power Location for Efuel controller

Is the purpose of this controller to vary pump speed with engine speed? Or just to turn on the pump? As mentioned a tach signal is hard to find. The only controller I looked at (not this one) would overdrive the pump for higher output. It would vary the voltage from 12 volts to 18 volts depending on engine speed. I think using a controller that would reduce the output of a big pump at lower engine speeds would be the ticket.

If not, whats wrong with using a wire hot in key start position to provide voltage to the relay coil while the starter is cranking and then using a hot (key on in run) fused wire to an oil pressure switch to provide power to the relay coil after oil pressure picks up, The relay would control a fused wire from the battery to provide fuel pump power.

Both key on in start and key on in run hot points are available in the in cab fuse block. The the fused wire for pump power can be tapped into the battery.

Re: Switched Power Location for Efuel controller

im using this attached link as a reference to locate tach wire under the hood. I have read that there are two similarly colored wires close to each other, but i planned on using the multi to pick the tach wire.

This controller does not vary output. i am considering going this route because as i understand this controller just needs power, tach signal, and a ground and i am all set. could very well be that i am wrong.

Re: Switched Power Location for Efuel controller

It is much simpler to just go with a Super Duty pump and just wire it where there is power anytime that the key is on.

You can't get much simpler than a hot wire and a ground.

Re: Switched Power Location for Efuel controller

The only problem is the tach on the power stroke tach signal is not the same as most cars. when I tied into the tach wire for my trans controller I had to adjust the signal by 12 to get the trans controller to accept the signal. Luckily the trans controller was able to make this adjustment. I looked at that controller and decided against it. This Is the one I looked at

I wanted to avoid running straight constant power to the pump in case of an accident, and I also wasn't comfortable drilling anywhere to get an oil pressure switch installed. However if the controller I have does not work I will end up running constant power as a temporary setup.

I was unaware that the tach signal for these trucks was different but now that im hearing it i am not surprised. do you know how exactly it is different? Since I have the revolution controller in hand I am going to try to run it and hope it adjusts accordingly as your trans controller did. if it doesnt then I will have to run constant power until I can look into the driven diesel controller.

Is the fuel bowl heater still my best bet for switched 12v power though? i get a little lost when it comes to anything related to electric/wiring on my truck.

Re: Switched Power Location for Efuel controller

It isn't hard to install a inertia switch in case you are in a accident where it will shut off the power to the pump.

Super Duties have it located behind the passenger side kick panel for ease of access, but you could install it anywhere between the power supply and the pump.

I had considered this as well but decided to go with this controller instead. It is good to know that there is an easy backup if i find out that it is not worth trying to use this part.
