electric pump conversion question

[ericwade381]

Hi guys wanting to do a e f uel conve rsion on my 88. just wan ted to make sure that I have the steps right I will delete the mechanical pump block off the hole put a frame rail electric pump On now my question once my pumps on does the fuel line from the tank to the electric pump will that go into the fuel filter and the metal line be deleted? Also do most people run the power to the injection pump solenoid or are there better places to run your power off of

There is a Post in tech on this

Don't draw it right off the ip, run that as a trigger to a relay.
I cut the end of my metal line off down where the nut would go into the lift pump, then slightly flared it, and just slipped the hose on and clamped it.

I threw in a couple parts store in-line 3/8 clear fuel filters right before the tank selector valves. One on each of the supply lines from the 2 tanks. They're enough to keep any bigger chunks of garbage from getting into the fuel selecter valves or electric pump.
Then just run a line up to the stock filter head.

Thanks guys I did see the posts I guess my question is with an electric pump do you only have one fuel line un like the mechanical where you have 2 the rubber line and the steel line

You have an "in" and "out" on any pump. In comes from the tank. Out goes to the filter head.

Ah ok thank you putting on a electric pump actually seems like it would be easier than a mechanical pump worrying about the arm in the right position and getting everything right?

This has some good information posted for you. Now a tip about installing the electric pump after the tanks switching valve. fuel is going to run down your arms probably reaching your pits.. Please don't allow that to happen. It burns there. Not a believer.. Yet it happen once. What I did after this was use a small C clamp on the rubber line before cutting it. You need 2 clamps. Only one way to not have fuel leaking out and thats to blow air thru the line from the engine back to the tank on both supply and return lines.

Thanks! Is the electric pump alot easier to start the truck when it's cold outside? What is the best way to go under the hood or a frame rail? The previous owner has a electric on it now connected to the mechanical but it's only for prime as I think it's on the timing like the glow plugs not sure if should just Re wire that pump and use it ?

I thought we covered this already and one of your other threads. Lol
Yes, it can help starting.
Pump location depends on the pump itself.

Lol thank you

All depends on current the pump and how it's done. If it was installed for the sole purpose of priming the system, it may not be up to full time fuel delivery. Need to get the model and find the specs. You want something in the 4-9 psi range and about 33 gallons per hour if I recall correctly. If it will do that, move the relay trigger wire from the gp controller to the fuel shut off switch. You have to run a relay on it in that configuration. It draws too much power to run it directly off the fuel shutoff solenoid.

Once you get it installed put up a pic of where you put it. I am going to put one on mine and I am debating between putting it under the truck or under the hood. If I put it under the truck I am going to put the filter down there with it.

 

[ericwade381]

Well I was going to just put a mechanical pump back on it just for a quick fix for plowing season but..the nut on the metal line that goes in to the pump rounded off it was so tight any tips on this one??

Laserjock, I see you mentioned "You want something in the 4-9 psi range and about 33 gallons per hour if I recall correctly." Is this because higher pressure will effect the IP? Can a high pressure fuel pump be regulated down safely? I have a HF 50 psi pump that I was planning to install, but your comments have me thinking now.
