Electric fuel pump / system upgrade finished

Hey well I finally finished my changeover to electric. It took a long time to do and man it's HOT here in FL.

I chose to use the 6.0L setup on my truck. I already had the fuel pump assembly and found a free fuel filter housing for under the hood so all I had to do was plumb everything up. The frame pump was easy but under the hood is where all the time was.

Got it running last night and WOW what a difference. She fires to life now and several little issues have been resolved. First my truck used to hesitate when in 4th gear at 1300 rpm with the converter locked. If I gave it the juice slowly it'd hesitate quite a bit till it got going but that's gone now it just takes off. Second was my idle used to waiver a little kind of slowly go up and down like 50 just enough to notice and that's gone too. Driving it just feels all around more peppy.

I plan on replacing the two return lines under the hood with matching braided lines soon. I'm satisfied and glad I did it. Oh also what are the rest of you with electrics running for fuel pressure??? I set it initially at 70 PSI but backed it off to 65 PSI now.

Looks good, but I'm confused on the pump(s)/filters. Are those SD's?

I run right a 70 on mine. I believe thats the highest these regulator go.

I run mine at 69psi. I've never though about using a 6.leaker fuel pump, but i wonder what they flow for fuel. It looks good though. why the use of the 6.leaker fuel filter bowl though vs frame mounted aftermarket filters/bases???

it looks like it has two filters? one at the pump and the other one on top of the motor?? what micron filtration does it provide? and as mentioned before, do you know the flow rate? I usually am a little conservative on my pressure, I keep it at about 62psi

Farm69 ... yep 6.0L fuel pump assembly and the fuel filter assembly. I had to cut off the oil filter portion and smooth it down and remove the bypass system from the under hood housing

strokin' ..... I used it for simplicity mainly. I already have one 6.0L ( Excursion ) so now I just buy the same kit for fuel filter changes. Our Ex has over 100k and never had an issue with the fuel pump or system. Not sure on the flow rates vs the older SD pump but I ran it with the system opened to flush the lines and it'll fill up a mason jar in nothing flat and I've had it as high as 80 PSI at first so it can't be too crappy.

Thanks for the comments .... I appreciate it.

97-psd .... yes you are correct one in the pump assembly and one mounted on the RH side of the valley on the intake bracket.

On the filtration Ford advertises their filters stop 4 micron and larger total. I called Wix and they spec'd the big one ( frame ) does 10 micron and the smaller one ( valley ) 5 micron.

Here are some specs I was able to dig up on the net .... Some items have been modified on the engine mounted filter housing. Thanks again for the comments.

Fuel Supply System

HFCM (Horizontal Fuel Conditioning Module) Fuel Flow
Fuel is drawn into the HFCM from the fuel tank via a supply line.
If the temperature of the fuel is below 50°F (10°C) it is heated by the fuel heater. The fuel heater shuts off at 80°F (27°C).
After being heated, fuel enters the filter housing via a one-way check valve.
Once in the filter housing, water is separated from the fuel. If large amounts of water are found in the fuel, a sensor in the separator warns the operator of this condition by illuminating a light on the dash.
Fuel is then drawn through the 10 micron fuel filter and into the fuel pump.
Conditioned pressurized fuel is then supplied to the engine mounted fuel filter via a fuel supply line. The pump has an internal regulator that limits fuel pressure to 100psi.
Fuel returning from the pressure regulator on the engine mounted fuel filter comes into the HFCM and a DTRM either allows the fuel to return to the tank or returns it to the unfiltered side of the fuel filter in the HFCM. The DTRM starts to open (recirculating fuel back into the pump) at 80°F (27°C) and is fully open at 50°F (10°C).


Engine Mounted Fuel Filter
A secondary fuel filter is mounted to the oil filter housing.
The secondary filter is a 4 micron cartridge style filter.
It also incorporates a fuel pressure regulator and an air bleed (to allow air to escape after a filter change). Fuel from the regulator is returned to the HFCM.

Just figured I'd post an update. It's been almost a year since my swap and have "0" complaints with this mod. I should have gone electric years ago. I'm just about to change the filters for the first time. The other day my water in fuel light came on!!! I was happy, I know that's weird, but now I know it works for sure. It worked on paper and it worked in my head but you know.
No leaks, no issues, and my fuel mileage has gone back to normal since I got over putting my foot in it all the time due to the truck actually getting the fuel now.

Later guys

Nice setup, I kinda wish I went this route instead of the Walbro 392.

This is why. I believe along the same lines. The rest of the 6.0 is questionable, but I have not heard anything weak about the fuel system in a stockish application. The availability of replacement filters while on the road is appealing, too. Just my $.02.

Nice write-up. That 6.0 pump looks goo on there...

And I kinda like how it has the pre-pump filter built in.

It may look pretty, but notice the allen head fitting toward the bottom? That's your WIF drain. And to change that filter down there means opening that WIF drain and letting all the fuel out or taking a diesel shower.

I don't know where his is mounted, but on the 6 leaker, if you have 4wd, then reaching the drain and filter lid is a pain with the front driveshaft in the way.

I've changed filters on both the 6.0 and 7.3, and personally prefer the simplicity of the 7.3 filter bowl and WIF drain. An electric pre-pump filter on the 7.3 can be done simple enough without taking a diesel shower. No offense to the OP, but he's already running a 6.0, so keeping all the filters the same makes it easier on him.

That's true Chris. I also looked up the price and that 6.0 pump assembly goes for $350... I could do a 7.3 electric pump and filters for less.

Brown Falcon I was lucky and picked up a NIB one on ebay for $135 years ago. They're available
