Going to efuel

[gnxtc2]

The relay terminals are numbered

Terminal 30 - +12v from battery (fused)
Terminal 87 - positive terminal on fuel pump
Terminal 85 - fuel heater wire
Terminal 86 - ground

Don't forget to run a ground wire for the fuel pump.

How should I prime the system? Obviously fill the filters, then leave the return fitting loose on the bottom of my regulator?

 

[gnxtc2]

Turn the key on. Don't disconnect any hoses. Let if run for a seconds to purge the air and set your fuel pressure.

sweet that's easy enough thanks for the quick reply

 

[RBernardi]

Does this look right? gnxtc2? The fuel heater wire you labeled to terminal 85 threw me off

 

[gnxtc2]

Yes....it's right. That oil pressure switch is junk and not reliable and fails. I eliminated it and just run the relay. These motors will run with no fuel pressure. There is a thread on this issue I made.

Ok so you ran your heater wire to #85 and supplied power while running and cranking is that ccorrect?

I'd like the pump to be off if I'm just sitting in the truck listing to music. If I eliminated all the old pressure switch would I have to wire in a toggle switch to turn the pump on?

I used the same heater wire to trigger my relay and no oil pressure switch.

Just use your accessory position of the ignition switch to listen to the radio. No power goes to the heater wire that way.

Yes....use accessory on key switch (turn key backwards)

Thanks a ton guys! I'm going to pull the switch and just run the heater wire to the relay and plumb a fuel gauge to the cab like gnxtc2 suggested.

I know it might be a little late, but this is how i did mine a while back, using the wiring harness from Bar None.

Well I got my system all buttoned up. Go to start the truck batteries are dead of course. Put the charger on them.come back in an hour, cranking but won't start. After about 15 minutes of trying it finally started, it ran for about 10-12 seconds that was it. Won't start again just cranks.

I've double checked the harness, all the connections are plugged in tight.
The pump is running good and I set the regulator to 65psi. Do you guys have any ideas?

 

[gnxtc2]

When you turn the key on, do you have fuel pressure? The 6 wire connector/harness is plugged in by the old fuel bowl? That harness contains the IPR wire. You cut the correct fuel heater wire?

Yes and yes, I'm going to pull the harness apart and spray the connection. With electrical contact cleaner. The other two wires on the fuel bowl harness I cut the ends off and taped back.

 

[RBernardi]

Well I sprayed all the harness plugs I took apart with contact cleaner, and it fired right up! I put a cheap air hose 3 way in the valley like Billy T did and its dripping so I figured it's cracked because the fittings are tight.

 

[gnxtc2]

I don't have an air hose three way. Air hose fittings are meant for air not liquid. I used -6AN "Y".

Sorry Billy, I was thinking of Tom S. write up. He used an aluminum threeway

 

[RBernardi]

Is it normal for it to be slow to start?

 

[old man dave]

You may have had some air to purge out.

 

[morefuel]

Mine seemed toy start slower after efuel not sure why. Batteries got replaced awhile after so they might have been getting weak.
